Ultrasonic thickness gauge - choose the best tool. Ways to correctly measure the length and diameter of the penis, what to do if the result is not satisfactory When to take measurements

There is nothing surprising in the fact that all men want to know the length and thickness of their penis. In addition, when penis enlargement with an extender and other devices, it is necessary to periodically take measurements to make sure that there is a positive result. How to measure penis size correctly? What to do if the results of measurements caused disappointment?

The size of the reproductive organ is an exciting topic for all men. Every member of the stronger sex has been measuring the penis at least once in their life.

The most common reason for taking measurements is simple curiosity. It is interesting for every man to know if the size of his penis meets the standards.

From a medical point of view, knowing the size of the reproductive organ is important. The fact is that with certain pathologies, accompanied by a change in the content of sex hormones in the body, men have a decrease in the penis. Typically, a micropenis is observed in men who have either an increased level of estrogen in the body or a reduced concentration of testosterone.

To get reliable indicators, it is necessary to measure the length and thickness of the penis correctly and carefully. An incorrect measurement can not only upset, but also frighten a man, falsely signaling a hormonal disorder.

You should also know the size of the penis in order to choose the right condoms. Different manufacturers produce contraceptives from two to four sizes. A man should choose condoms that best match the size of the penis. Incorrectly selected contraceptive during an intimate act can break or slip off the penis.

A common mistake in assessing the size of the penis

Some men misperceive the size of their reproductive organ, as they make a mistake in visual assessment.

Usually, the representatives of the stronger sex look at their penis in the usual way - from top to bottom.

And this is wrong, because with this method of viewing, a false impression is created that the penis is too small.

The fact is that it seems smaller when viewed from above due to the fatty layer in the pubic area.

To see how big the penis really is, you need to stand sideways in front of the mirror. From this angle, a man can see that the penis is much longer than when viewed from top to bottom. It is from this angle that the size of the penis is perceived by the sexual partner of a man.

Preparation for measurement

Before measuring the penis, you need to create comfortable conditions around yourself. The size of the penis can change under the influence of the following factors:

• air temperature;
• time of day;
• state of mind;
• physical and emotional fatigue;
• level of arousal;
• time interval after the last intimate act.

To get the right results, you need to take measurements in a calm and relaxed state of mind. The procedure should be carried out in a warm and comfortable room. To obtain a reliable result, it is recommended to take measurements for several days in a row at different hours, and then calculate the average value.

Measuring the length of the penis

Men tend to exaggerate or underestimate the size of their penis, so you should not trust your eyes. It may seem to a man that he is, and the ruler will give out completely different information. How to measure penis size to get the correct data?

It is recommended to apply the ruler not to the top, but to the side of the penis, so the measurement becomes more accurate..

In lateral measurement, pubic subcutaneous fat does not interfere. But how to take measurements for men whose penis is curved?

In this situation, the length is the shortest distance from the head to the base of the penis.

Length measurement is carried out only when the member is in an erect state. Medical experts say that taking measurements when the penis is relaxed is pointless. The fact is that an erection can significantly transform the sexual organ.

In some men, during an erection, the small penis stretches surprisingly strongly. A large penis in a state of excitement may, on the contrary, remain unchanged. It turns out that an erect small penis is longer than an unexcited large penis.

Measuring the thickness of the penis

The thickness of the penis is the circumference of its shaft. To take measurements, you need to take a cord and a ruler.

The shaft of the penis in the central part or closer to the base is wrapped around with a cord.

On the lace, marks are made with a marker in the places where the circle begins and ends.

The distance between these marks is measured with a ruler. The resulting number is the thickness of the penis.

But how to take measurements correctly for men whose penis in different parts of the trunk has an unequal thickness?

It happens that the penis is thicker at the base, and thinner near the head, or vice versa. In this situation, you have to make several measurements in different parts of the trunk.

Measurements are taken at the base and near the head of the penis. Then the average value of the thickness is calculated: the resulting numbers are added up and divided by two.

Diameter measurement

it's easy to calculate. The diameter is the distance between the two most distant points on the circle.

The parameter is calculated according to a simple formula, known since the school bench: the circumference is divided by the number pi, that is, by 3.14.

For example, if the circumference of the penis is 12 cm, then the diameter is almost 4 cm.

But keep in mind that the male organ in cross section is not a perfect circle, so the diameter value is not exact, but approximate.

Normal penis sizes

After measurements, it remains for a man to find out what penis size is normal in order to compare it with the size of his dignity.

1. An erect penis shorter than 10 cm is considered small. In Caucasian men, the normal penis is 10-16 cm long.
2. A penis longer than 16 cm is considered large. The average penis thickness of Europeans is 11-14 cm.

It should be borne in mind that the size of the penis depends on the age of the man. In older men, blood circulation in the genital area deteriorates, so the cavernous bodies shrink, the penis thins and shortens.

Member does not meet the standard - what to do?

After measurements, many men worry that their penis is not as big as they would like.

But no one is worried that, although during sex, women experience discomfort and even pain from penetrating a large penis into the vagina.

In fact, because of the length of the penis, men should not be upset. For most women, the length of the partner's penis is completely unimportant, since it does not affect the intensity of sexual pleasure.

But important for women is the thickness of the penis. The thicker the penis, the more actively it rubs against the walls of the vagina, the more pleasure the partner gets.

But if a man is convinced that the quality of his sexual life is low due to the insufficient size of the penis, then he can use effective and safe methods of enlarging the reproductive organ. Fortunately, there are many such methods offered today.

A man can try increasing ointments and gels, massage devices - and vacuum, stretching exercises. If the penis is so small that it is difficult to enlarge it in the above ways, then the only option remains - surgical intervention. However, the operation to increase the penis is quite dangerous and unpredictable, it is prescribed only as a last resort for medical reasons.

Anthropometric measurements make it possible to determine the level and characteristics of physical development, the degree of its correspondence to sex and age, existing deviations, as well as the level of improvement in physical development under the influence of physical exercises and various sports. Thus, anthropometry includes the determination of length, circumference and other indicators. Why does a person need it in life? With the help of anthropometric indicators, it is possible to control the dynamics of physical development, the effectiveness of physical exercises. You can also learn how to determine the size of clothes. Most modern computational and graphical methods for designing clothes provide as initial data information about the dimensions of the body (dimensional characteristic of the figure) of a person and allowances (allowances) for free fitting. Size is an alphabetic or numeric code corresponding to certain linear parameters of the human body, or that part of it for which this piece of clothing, accessory or shoe is intended. Typically, the size is printed on a tag attached to the garment or accessory, and in the case of shoes, it may be printed on the sole or insole.

What anthropometric indicators are used to determine the size of clothes and shoes, how to measure them correctly

Growth. In order to correctly measure your height, you will need outside help, a ruler and a pencil. Become barefoot with your back against the wall, trying not to hunch over. The ruler is placed on the head, a straight line is drawn from the top of the head to the wall, where a pencil mark is made. Now, using a ruler or meter, calculate the distance from the floor to the mark.

Chest girth. You will need a flexible tape meter. Wrap a centimeter around your chest so that it passes through all the protruding points. To obtain an accurate result, repeat the measurement procedure again.

Waist circumference is also measured using a centimeter. When measuring the waist, do not pull in the stomach, otherwise the indicator will be incorrect.

Hip girth. It is measured approximately 15-18 centimeters below the waist at the most protruding points of the buttocks.

Shoe size. The size of a person's foot is determined by two parameters - the length and width of the foot. We determine our sizes. First - measure the length of the foot. It is recommended to do this at the end of the day, because. legs get trampled and get bigger. Stand on a piece of paper and circle your foot with a pencil. To determine the length of the foot, measure the distance between the outermost points on the drawing. Measure both legs and choose the longest length. Round the result to 5 mm and find your size in the table.

The ultrasonic thickness gauge is considered the most popular type of such devices due to its affordability and ease of use. Moreover, there are many modifications of it, which means that both professionals and ordinary people will find a model for themselves. We will understand the features of this device together with you.

Ultrasonic Thickness Gauge - Measuring Principle

The very name of the device already hints that the main working tool is a sound wave of ultrasonic frequencies. The measurement process is quite fast and can be described as follows. On the body of the device there is a sensor that is sensitive to ultrasound, it is built into the probe, which is attached to the surface under study. A place is selected in which to measure, for example, paintwork, we press the probe to the selected point, we give a command to the device by pressing a button.

The probe emits an ultrasonic wave, it passes through the coating, reaches the surface that is under it, and reflects the pulse back. Usually such a material is metal, very often this is the main condition for a substrate for a successful measurement. The reflected wave hits the probe sensor, a kind of echo, and is converted into an electrical impulse. Then the electronics digitizes it and analyzes it, using formulas it calculates the path, i.e. the thickness of the coating, which the ultrasound managed to pass.

This principle works not only for coatings with a metal backing, but also for measuring the thickness of the metal itself. The impulse is simply analyzed until it ceases to be reflected, which means that it has passed through the metal, hence the result is given. But in general, such thickness gauges measure almost all materials popular in everyday life and industry: ceramics, plastic, glass, and so on. The resolution of the method does not allow only the measurement of paper, wood, foam or, because these are either too thin samples or too wide.

The approximate measurement range starts from 0.08 mm and reaches a thickness of 635 mm, the accuracy of the best instruments is in the region of 0.001 mm. All devices of this class rarely make an error that exceeds 3%, even the most budget ones.

Specifics of the ultrasonic thickness gauge

Its first and most striking advantage is considered to be a non-destructive method of taking readings. Today, it is extremely rare, except for special laboratory conditions, that we have the opportunity to dissect a sample for research. We cannot cut, erase or scratch the coating in depth in order to then measure the thickness of the damage. That is why the ultrasound device has become so popular in many areas. But he is not the only one who does not destroy the coating when measuring, what else did he attract users with?

Indeed, this is far from its only charm, and only thanks to other advantages it has become, maybe not always the best, but the best device for both the budget class (especially popular in this consumer range) and many professional fields. For example, another significant argument in its favor is the ability to measure the thickness of a coating or metal where only one side of the sample is accessible, that is, it cannot be clamped between the measuring bolts. Let's say we need to measure the thickness of the pipe, naturally, attach the measuring rods from the outside, and then from the inside, and we cannot take the measurement. Just with the help of an ultrasonic thickness gauge, the problem is solved, since only the outer side is enough for us.

Moving on, if you have already looked through at least one catalog of measuring instruments for coating thickness, then you have appreciated the compactness of ultrasonic thickness gauges. The simplest ones, for household needs, generally look like calculators and fit easily in your pocket. Rarely you will find such miniaturization in a line of devices with a different principle of operation. In addition, you have already guessed that measurements are taken quickly, and brute physical strength is not needed at all, which means that even a girl who has never specialized in this field of research can measure. The absence of physical costs and saving time is recorded in the next pluses.

Yes, the simplest thickness gauges do not require handling skills, but what about professionals, they are unlikely to have enough of the minimum programmed functions. In this case, you need to buy a more “smart” device that has programming functions for various modes and settings. And the choice of such devices is really great, which is why the universality of the ultrasound approach in measurement is another advantage. And, despite the ingenuity of setting up a professional device, it will be possible to take measurements all the same - literally in a second.

And the last pleasant circumstance is the ability to synchronize with more organized devices for processing arrays of data, you also often find a good amount of memory and minimal ability to collect statistics in the thickness gauge itself. But the output and collection of results on a computer, for example, in order to quickly process statistical data, is a significant plus. And although ultrasonic devices are not the only ones with this ability, if they did not possess it, their popularity would decrease.

Ultrasonic metal thickness gauge - features of the model range

When choosing an ultrasonic metal thickness gauge, you can get a little confused, so we will try to trace the evolution of the complexity of instruments on the line of metal gauges. Perhaps this will simplify the course of your considerations when buying and help you find the optimal ratio of the desired set of functions and price. Let's start with the simplest representative, the series A1207. This "baby" is the most affordable, has a minimum set of functions, and is very portable. It measures wall thickness with fairly democratic requirements for their quality, it is usually estimated by roughness and radius of curvature.

His fellow series A1208-1210 get a slightly wider range of functions, this is more often due to the variety of measured materials. And models of an even higher standard of type A1270 become smarter, acquire special analyzers from the manufacturer for help, and also impose even lower quality requirements on the surface, they can even tolerate the presence of a gap or a coating that is unnecessary for measurement. This means that you do not need to clean and free the surface. Thickness gauges Bulat 1S and Microgage have additional functions not only in measurement, but also in the design of the case or extended configuration, for example, the first option has several sensors, and the second model has a protected case, which is important for electronics if you have to work in a not very dry room.

There are devices not only of high accuracy, but also with the A-scan function, which allows you to build a surface survey graph, for example, series 35. So you can find out the residual strength of the metal subject to corrosion. Even more complex devices have their own “brains” capable of collecting statistics and processing them, storing results, and are distinguished by high accuracy and breadth of the materials studied, for example, 37DL Plus, but their cost is quite "biting".

It is important not only to choose the design and color of the structure, but also to correctly determine the dimensions of the paintings for each room. To do this, you must first make accurate measurements of doorways, and only then, based on this information, calculate the dimensions of each door block.

Standard and non-standard doorways

In typical high-rise buildings, doorways usually have a standardized width depending on the room:

• bathrooms and bathrooms - 63 ... 76 cm;
• kitchen - 77 ... 87 cm;
• living rooms - 88 ... 110 cm;
• opening for the front door to the apartment - 90 ... 110 cm.

The height of the opening in kitchens and rooms varies from 204 cm to 210 cm, and in bathrooms and toilets there are often passages 194-203 cm high, which requires the installation of lower canvases or changes in the dimensions of the installation site.

Passages of non-standard width and height are usually found in old buildings and private cottages. Also, often as a result of redevelopment, even in standard apartments, instead of standard openings, wider or higher aisles are equipped.

You can take measurements of doorways by inviting a professional measurer. But if you decide to measure yourself, then you must first learn the rules for performing this operation - how to correctly measure the width of the opening, how to correctly measure the height of the opening and how to measure the thickness of the wall.

How to correctly measure the width of the opening?

The width of the doorway is measured at three points - top, middle and bottom. From the values ​​obtained, the minimum result is selected, and it will be the width of a particular doorway.

In typical apartments, the following standards for the width of door structures are usually followed, setting:

• in the kitchen - canvases 70 cm;
• in the bathroom and toilet - products 60 or 55 cm;
• in rooms - models 80 cm;
• as a second entrance door - 90 cm options.

Most major manufacturers produce door leafs adapted to the dimensions of typical passages. The width of the canvases is usually equal to 600 mm, 700 mm, 800 mm, 900 mm. Some brands also have models with a width of 550 mm and 400 mm, but their choice is small. Such a variety makes it easy to choose a canvas for a typical room.

If you have old doors installed and you are satisfied with their width, then you can simply measure the parameters - let them correspond to the dimensions of the new door leaf.

How to correctly measure the height of the opening?

The dimensions of the opening in height must also be measured at three points - along the side slopes and in the middle. From the obtained values ​​​​the smallest is chosen, for this parameter it is necessary to select doors.

The standard height of the door leafs is 2 meters, they fit into the installation place with a height of 204 to 210 cm. With a higher passage height, the width of the standard trim may not be enough to mask the junction of the door frame and the wall. In this case, wider architraves are used to decorate the door structure or a portal with a capital is installed.

In the model range of some brands, you can find models with a height of 1.9 meters. They are installed in bathrooms and toilets. Such canvases are suitable for aisles with a height of 203 cm or less.

IMPORTANT!

Even if you are sure that the repair in your house is done perfectly, you should still measure the doorway at three points in height and width. Otherwise, you run the risk that the finished door unit will be wider or higher than the installation site, and you will have to bear unplanned costs.

How to measure wall thickness?

To determine the wall thickness, measurements are taken at three points and the largest of these values ​​\u200b\u200bis chosen. The standard for doorway wall thickness is 6 to 8 cm, which is what most manufacturers of interior doors are guided by.

If the thickness of the wall is greater than the width of the box beam, it is necessary to install door extensions. These are strips of various widths, with the help of which door slopes are formed. They have the same texture and color as the entire door structure.

Door extensions not only give the opening an aesthetic appearance, but also protect the slopes from scratches and abrasion. Therefore, do not save on their installation.

When to take measurements?

An accurate measurement of the dimensions of the doorway is carried out after finishing the walls and laying the decorative flooring. Otherwise, there is a risk that the selected doors cannot be installed due to the fact that the opening is smaller than the dimensions of the door block.

But it is necessary to pre-measure the doorway even before performing a rough finish. This will allow you to choose the size of the opening in accordance with the line of standard canvases. And then you will not have to overpay for interior doors of non-standard sizes.

It is not difficult to reduce the size of the passage; brick, drywall or wood are usually used for this. The expansion of the installation site can affect the strength of the wall, this operation must be carried out with caution, strictly observing the established building codes.

Why are measurement errors dangerous?

Professional measurements are a guarantee that the doors you have chosen can be installed quickly, without problems and without additional financial costs. After all, it is far from always possible to increase the size of the installation site, especially when it comes to a load-bearing wall. And if the finishing of the walls has already been completed, then to narrow the passage you will have to spend a lot of effort and additional money.

If you are not sure about your measurements or do not want to take risks, then it is best to purchase doors with a turnkey installation. In this case, the seller is responsible for the correct measurements, so you can be sure that each doorway will correspond to the dimensions of the leaf, and if there are errors, all replacements will be made at the expense of the installer. You can order a turnkey installation service in the online store of the Porta Prima factory or in sales outlets.

Swing door dimensions

Determining the dimensions of a swing-type door is carried out taking into account the height and width of the leaf, the thickness of the door frame, the presence or absence of a threshold.

The passage parameters for mounting a swing door block are calculated according to the following rules:

• opening width = web width + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm;
• opening height when mounting doors without a threshold = leaf height + frame thickness + mounting gap 2 cm x 2 + technological gap 3-5 mm;
• passage height when installed with a threshold = web height + box thickness x 2 + mounting gap 2 cm x 2 + technological gap 3-5 mm.

Using these simple formulas, you can easily calculate the dimensions of an interior door for each room in an apartment, house or office.

Don't forget about extras. Additional strips are available in different widths, they can be joined together and cut along, which allows you to choose a decorative design for a wall of any thickness. With their help, you can also mask the vertical deviation of the slope; for this, the bar is cut off in the form of a wedge.

Sliding door dimensions

Sliding doors today are increasingly replacing traditional hinged designs.

The dimensions of sliding systems depend on the type of mechanism used:

• sashes move parallel to the wall;
• the canvas goes inside the wall into the cassette;
• panels overlap when opened.

For example, for sliding door structures, the leaf should be 5-7 cm wider than the opening. This is due to the fact that such doors, in fact, perform the function of a screen and should block the passage from the side. Therefore, the leaves can be significantly wider, but not narrower than the width of the passage.

If a sliding door-pencil case is installed, its width is selected so that the canvas protrudes slightly from the wall. This allows you to conveniently close the doors.

For wide openings, designs of two or more wings are used, which are selected from standard-width canvases. In this way, it is possible to block passages of almost any size.

Non-standard doorways - solutions

If your apartment or house has non-standard sizes of openings, then the best solution would be to narrow or expand the passages to standard dimensions. This will allow you to install standard interior doors instead of ordering custom-sized canvases.

The advantages of installing door blocks of standard sizes include:

• fast installation time - canvases are available in stock;
• much lower price than models of atypical sizes;
• a wide range of designs and colors.

If the selected canvas does not fit in the height of the doorway, you can trim it. It is undesirable to do this on your own, since you need to use a professional tool. It is best to contact a company that provides such services.

In some cases, it is not possible to change the dimensions of the passage for technical or financial reasons. Then you have to order the manufacture of non-standard doors. They cost 30-40% more than mass-produced products, and their production usually takes several weeks.

Hello, dear online audience of my autoblog! I am with you again, Ilya Kulik, and in today's article we will talk about how to use the thickness gauge of car paintwork.

Preparation for measurement

So, you know the properties of your thickness gauge and the properties of the body of the car you are interested in. You can begin to examine it, but first you need to perform some preliminary preparations.

Device calibration

For the most accurate readings, it is advised to calibrate the thickness gauge before the measurement session. This refers to those devices that support this operation (there are so-called self-calibrating models). The meaning of calibration is to indicate to the device the exact value of the reading manually by means of a reference measurement in a special mode.

What is needed for this? Calibrating thickness gauges come with two, three or more calibration plates made of metal and plastic. The minimum that is needed for calibration is one metal plate (simulating the base of the body) and one plastic plate (simulating the body paintwork).

You can pick up any metal plate (not necessarily from the factory kit). If the device works only with ferrous metals, then a steel ferromagnetic plate is needed, and if the device is universal, then it can additionally be calibrated using a diamagnetic aluminum plate. The main thing is that both plates have a smooth and clean surface.

But plastic calibrator plates are thickness standards and it is better to use those that are included with the device. Usually this is one standard thickness of 102 microns. But sometimes several additional ones are added to the main standard, with different thicknesses, to double-check the calibration performed.

Calibration procedure

To carry out the calibration procedure, prepare the necessary plates (on the new ones, remove the protective film), turn on the device and reset the device to factory settings: usually you need to test the metal plate and press the “0” key, but this needs to be clarified in the instructions for your model .

For example, for a pressure ET-111, you need to act in this way, but the trigger ET-11S is reset to the primary settings in the off state, while pressing the trigger and the "0" key.

During this test measurement, the error level will be displayed on the screen. If this value is "0", then no calibration is required.

For any other indication, proceed according to the following points:

• Place a plastic standard on a metal plate and carefully measure the thickness.
• Press the calibration mode key "K" ("CAL" or something similar) on the instrument panel.
• With the help of two calibration keys (type ><) выровняйте значение на экране в соответствии с эталонным – 102 мкм (оно указано на эталонном пластике).
• Press the calibration mode key again.
• Everything, the thickness gauge is calibrated - it's a bit like setting the time / date in a car electronic clock.

You can check the set calibration: its values ​​should not differ from the reference values ​​by ±2-3 µm, which is not considered a failure.

The main calibration is carried out on a steel ferromagnetic plate. In principle, this can be limited to a universal device, but for ideal tuning, the described procedure must also be carried out on an aluminum plate, in the corresponding nFe mode.

For better understanding, watch this video, which shows the process of calibrating the ETARI ET 111 thickness gauge:

Do you know how thick your car's paint should be? - Paint thickness chart

Your instrument is calibrated and ready to go. But first you need to familiarize yourself with the table, which shows the average paintwork thickness limits for your car brand.

Here I have given a table with the main values, but on the net you can find more detailed data on factory paint thicknesses. However, it is best to take these values ​​not from the tables, but from the technical documentation of the vehicle being examined.

The thickness is indicated in micrometers (MKM).

You must remember that the factory paint thickness range of most cars is 70-150 microns, and the most common values ​​are even narrower - 80-130 microns.

But there are the following nuances:

• The factory thickness of the coating can be different on different parts of the body, which depends both on different technological methods of application and on the physical properties of the paint. For example, in the middle of the roof of a car, the thickness of the paintwork is usually less than at its edges.
• There may be a difference in values ​​between different individual elements of the body, but for symmetrical places of paired elements it should be the same.
• Despite the allowable differences in the thickness of the factory paint on different elements, these values ​​\u200b\u200bshould not exceed 50 microns for the smallest and largest values. And on average, this figure should be 20-35 microns (excluding 2-4% of the permissible error of the thickness gauge, consider this as well).
• You should also know that the factory thickness of the paintwork of the inner surfaces of the body is thinner than the outer ones by about 40-60 microns, keep this in mind.

You also need to take into account the features of some new models of thickness gauges. They have the useful ability to indicate to the instrument the expected range of upcoming measurements, which drastically reduces the likelihood of errors from hand tremors or other factors.

Useful reference:

In order for you to have a figurative idea of ​​​​the thickness of the paintwork, know that the average factory coating approximately corresponds to the thickness of a human hair, which is 75-110 microns.

Measurement procedure

The direct measurement procedure is not particularly difficult - any driver can handle it.

Here, one should take into account the differences in turning on devices for different models: trigger and some old-style pressure devices need to be turned on without touching the sensor to the surface being examined, and modern devices automatically turn on when the sensor comes into contact with something solid.

Attention! Do not point the activated sensor into the eyes of a person from a close distance!

Everything else is pretty simple:

• The included thickness gauge is pressed against the surface under study, and it will display the measured readings on the screen. In trigger models, to initiate measurement, you need to press and release the trigger, in push models everything happens automatically. Keep in mind that the device must be held firmly and evenly so that the sensor is in contact with the enamel without distortion.
• You can examine the surface pointwise or in continuous measurement mode: without releasing the trigger or simply continuing to guide the pressure device along the paintwork in the desired areas - the readings will change.
• But in order to derive average thickness indicators for a car, it is precisely point measurements that are needed: each segment is examined separately.
• Elements are conditionally divided into 5 parts (4 in the corners and 1 in the middle). Of course, more measurement points can be taken, especially if there are already any suspicions in a certain area.
• For each point, 3-5 measurements are taken, which are recorded on paper or.
• Each point is measured not in the same place, but within a radius of about 10-20 cm around the selected center - this will achieve a greater average accuracy.
• After that, for each measurement, the arithmetic mean value is calculated - the sum of the readings of all measurements of the point, divided by the number of measurements of this point (elementary school arithmetic).
• As a result, you will get 5 arithmetic mean readings for each body element, by which you can judge the degree of thickness discrepancy with the factory parameters of local areas (roofs, wings, doors, etc.).
• From these 5 indicators, you can easily calculate the arithmetic average of the paintwork thickness for each segment, and on the basis of this, make a calculation for the entire machine.

And now the same thing, only visually:

How to use the thickness gauge first part:

What thickness values ​​​​are considered a discrepancy with the factory

It is not difficult to determine, using the thickness gauge readings, not factory painting, and even more so the place of puttying, if you know all the initial data.

The practice of surveying used cars shows that usually in cases of repainting / tinting, the values ​​for the device are 2 or 3 times higher than the standard factory ones.

In fact, we can say this: if there is a discrepancy from hundreds of microns and above, then this is guaranteed not to be the original coating. Moreover, a discrepancy exceeding 160 microns indicates a putty layer.

An ordinary additional layer of paintwork gives an extra 100 microns to the existing one. This means that if the total reading is 180-260 µm, then this is indicative of overpainting/touch-up. And if it is higher, then this is already painting with puttying. The thickness of the putty can sometimes have not micro, but macro values, which the thickness gauges are not able to display on the screen due to going off scale.

How does a car painter contrive so that you do not notice anything

You also need to take into account the possibility of all sorts of tricks car bodybuilders. For example, they can specifically reduce the factory thickness of the paintwork with abrasive polishes before painting. Because of this, in case of inept work, the thickness gauge shows values ​​​​less than the factory ones (for example, 80-90 microns from 110-120 initial ones).

If you want to know more details about working with a thickness gauge, then watch this video, where an experienced outbidder reveals the features and secrets of such a process using the example of examining a popular model of a domestic car:

• Sometimes sellers go for such a trick: they don’t wash a dirty car on purpose in order to make it difficult to inspect it with a device.
• You should be aware that for some premium models (Mercedes and some others) the factory thickness of the paintwork is higher than usual and reaches 150-250 microns. In this case, you need to look at the documentation for the car.
• Keep in mind that for older cars, even if for some reason they still have factory paintwork, body elements located horizontally can have a significantly lower thickness, because when washing these places rub more strongly and the paint on them thins out over time, especially for those who like to keep the car clean, which in itself is commendable, of course.

Conclusion

So, now you know how to prepare the thickness gauge for work and take measurements with it, taking into account all the features and nuances of this type of machine inspection. When asked whether it is worth buying and using this device, you can answer with a confident “yes”, because this will save you a tidy sum at the auction if you find bits that the owner kept silent about.

Especially if you choose the device itself inexpensive, but fully suitable for accurate measurements, like All-sun EM2271- then you will be seriously instrumentally armed, losing almost nothing in money.

Tell us how you use the thickness gauge. If you have your own chips, then I and everyone else will be glad to know about them. If the infa is worthy, then I will supplement the article with it!
