For users in unfamiliar industries, do you know what the Thickness Gauge is used for?

Thickness gauges must be familiar equipment for practitioners in industrial work, especially in some manufacturing industries, such as automobile manufacturing, whether you have used this equipment or not. What are the main uses of the Thickness Gauge?
The Thickness Gauge is mainly used to measure the thickness of coating or coating. These thicknesses are very important for manufacturing and processing. For example, in the automotive industry, the coating is mainly sprayed by some equipment, and the thickness is sometimes unstable. If the coating is sprayed too thin, the smoothness of the paint surface will be affected, and its stability will also be affected, and this problem can be solved by knowing the thickness.
Thickness gauges are also used for data recording. The design and manufacture of any product requires continuous improvement. How to improve it depends on some main real-time data during production. In order to obtain these data, it is necessary to use a Thickness Gauge to test these data.
