The distinction between destructive and non-destructive coating thickness gauge
The difference between the coating thickness gauge and the non-destructive coating thickness gauge is mainly as follows. Coating thickness gauges and non-destructive coating thickness gauges are both used to measure the nominal thickness of materials, but there are certain differences between coating thickness gauges and non-destructive coating thickness gauges. Let's introduce the difference between the coating thickness gauge and the non-destructive coating thickness gauge in detail.
The difference between coating thickness gauge and non-destructive coating thickness gauge:
Coating thickness gauge, mainly used in the surface treatment industry, is used to measure the coating thickness of metal or plastic surfaces.
Non-destructive coating thickness gauges are divided into two types: magnetic and eddy current, and there is also a dual-purpose type of magnetic eddy current. It is often used to measure the thickness of the nominal coating where the substrate is metal, so it is also called a coating thickness gauge.
The magnetic thickness gauge is designed to measure the thickness of the coating under magnetic metals such as steel (except for magnetic metals such as steel and nickel), and the coating under non-magnetic copper, aluminum, tin, etc. cannot be measured. The eddy current thickness gauge is designed to measure the thickness of the insulating layer on non-magnetic metals, such as copper and aluminum (the coating must be non-conductive).
The above content introduces the difference between the coating thickness gauge and the non-destructive coating thickness gauge, and I hope it will be helpful for your application.
