When a person is going to buy a car from the previous owner, he will definitely be interested in a number of important points: whether the vehicle has been in an accident, whether all body elements have been factory-made or some of them have already changed, have they been repainted, and if so, why ? It is almost impossible to correctly answer these questions even with a thorough visual inspection. This will help special equipment called a thickness gauge. This device is designed to calculate the thickness of the paintwork.
There are frequent cases when sellers try to hide the fact of replacing certain parts from a potential buyer. In order for the car to have an attractive appearance, they make the so-called pre-sale preparation, which consists in repainting the body parts. This allows you to achieve an excellent visual effect, outwardly it will seem that the car has not been in a traffic accident, has not been painted, and so on.
On the Internet, you can find the average size of the layer of paints and varnishes for each make and model of car. Armed with this knowledge, you can use a thickness gauge to determine this parameter on most of the main elements of the vehicle for several minutes and calculate where the putty or an additional coat of paint has been applied. Automobile stores today offer their customers a wide selection of thickness gauges, which differ from each other by the principle of operation, functionality and a number of important points.
Buying the best model is not as easy as it seems at first glance. To make this task easier for you, we decided to devote our today's review to just these products. However, before starting to consider specific models, let's figure out what the equipment is based on, what capabilities it has, and so on. This is where we start.
Summary of the rating:
What do you pay attention to when buying a thickness gauge?
The simplest device for calculating the thickness of a layer of paints and varnishes can be done with your own hands - they take an ordinary magnet and wrap it in a cloth (this protects the paint layer from scratches). The principle of operation is quite simple - the magnet will hold on normally painted surfaces, and will begin to fall off the putty. This is due to the weakening of attraction due to non-magnetic repair material. A serial gauge thickness gauge works by a similar principle. It is quite simply arranged, therefore, it will serve for a long time. Simplicity of design provides low cost, there is no need to provide power. However, such a product has a number of significant drawbacks that cross out all its advantages: it is not very sensitive and is not able to provide good accuracy of indicators.
A more advanced design is the electromagnetic thickness gauge, which works by creating a magnetomotive force on the winding. Here measurements are made by calculating changes in the electromagnetic field - for this, a Hall sensor is used.The accuracy here is much higher, as well as the sensitivity of the device, but the cost also increases.
The most expensive, but at the same time the most accurate equipment, is considered an ultrasonic thickness gauge, whose work is generally not associated with the use of magnets. With this device, you can measure the thickness not only on metal, but also on plastic elements of the body, for example, on bumpers. The principle of operation is based on the passage of a high-frequency sound signal through elastic and solid media and its return back to the device - an echolocation base. Such products are usually used by professional craftsmen involved in the restoration of body elements after an accident.
Choosing models for our rating of the best automobile thickness gauges of 2019, we were guided not only by the above factors, but also by user reviews, as well as the ratio of price and quality of equipment, so that it would be affordable for most of our readers. Now is the time to analyze the useful characteristics of such devices.

2. Etari ET-10P
One of the most budget versions among the products of this class. The device is able to function only on ferrous metals with magnetic characteristics. The product works very reliably, in shape resembles a gun. The interface is fully Russified, the device is able to work normally at temperatures from -25 degrees. It can be used not only to check the thickness of the coating layer, but also in industrial production in order to control the thickness of various kinds of coatings deposited on magnetic substrates.
The inclusion and production of measurements is carried out by pressing the trigger type key. Calibration is carried out independently - for this a special button is provided, which will have to be held for a rather long time, so it is almost impossible to reset the settings. The fact that measurements are made exclusively on ferrous metals does not interfere at all, since such a function is quite enough for most cars located on the domestic secondary market. The maximum measurement error with such a device is only 1 micrometer, the internal memory is enough for 255 measurements.
