How to use a thickness gauge

To take measurements, attach the device to the surface of the machine

The device is not difficult to use. To understand what thickness the coating is applied to the base, you should attach the device with the right side to the car body.

Attention! In order for the measurements to be accurate, it is necessary to apply the device in 4-5 places and compare the indicators.

First of all, it is recommended to check the most basic parts of the car - hood, roof, wings. In one of these places, the device may indicate a change in the coating layer. This will indicate earlier accidents and repairs. Add measurement points so that the data is correct.

A thickness gauge is a device that can protect you from buying a car with hidden defects. When choosing a device, be sure to consult with a specialist. Knowing which thickness gauge is better, you will certainly get the desired result. Many companies today rent appliances, so if you need it once, then it makes no sense to spend big money.
