The development of small businesses has revealed the need for entrepreneurs in various services and products, including tools. One of the services is the determination of the thickness of the protective and decorative coating on various surfaces. For example, it is necessary for buyers of used cars, in order to identify the repainting of elements of the car, if the latter has been in an accident. Determination of the size of the coating is performed using a specialized tool - thickness gauge. There are many manufacturers on the market, offering various devices with different characteristics from each other. Which one is the best? How to choose without overpaying? We invite you to read and consider the model closer.

Thickness gauge which company choose
Thickness gauge - a device for measuring the total thickness of a part or workpiece, as well as a protective and decorative coating (primer, putty, mastic, varnish, paint, etc.). The tool allows you to determine the size of the surface layer without disturbing it.
The device according to the principle of operation, purpose, method of measurement is divided into:
- ultrasonic;
- magnetic;
- eddy current (electromagnetic);
- combined;
- universal;
- mechanical.
The review was prepared on the basis of the analysis of customer feedback and users of devices, as well as on sales ratings in retail outlets.
The principle of operation of the ultrasonic thickness gauge is based on the passage of a sound signal through the coating, reflection from the base, followed by registration by the sensor. The range of error of the device ± 3%. Determined coating size of 0.08 mm.

The basis of the magnetic thickness gauge - the properties of magnets. Non-magnetic coatings applied to a magnetic base are measured. The calculation is made by changing the force of attraction between the magnetic surface and the magnet of the device.

5. Blue Technology (Poland)
The effect of the eddy current gauge is based on the creation of eddy currents in a conductive base. The Foucault currents, in turn, generate their own electromagnetic field, which is opposite to the primary one. The latter is produced by the coil of the instrument. The generated secondary alternating magnetic field is captured by the instrument, the coating thickness is calculated. The feeler gage steadily works only on conductive bases - ferrous metal, non-ferrous metals and alloys.
