coating thickness gauge

Digital coating thickness gauges from many of the methods for measuring layer thickness? The older they are, the more reproducible they are. These devices usually find out the thickness by creating an eddy curent flow in the desired layer. When buying a layer thickness gauge, you should first pay attention to the surface material on which the desired layer is placed from the point of view of being iron or non-iron (ferrous or non-ferrous). Of course, some thickness gauge companies can measure Thickness is provided for both ferrous and non-ferrous bases in one device. In the next step, we can refer to separate and assembled probe models. The accuracy and range of measurement in microns are also factors in selecting these equipments.
