Classification of coating thickness gauges

- Feb 26, 2018 -

Coating thickness Gauges According to the principle of measurement usually has the following three types:

Magnetic Thickness Measurement Method

The measurement of the thickness of the nonmagnetic layer on the magnetic Guide data is usually as follows: steel, iron, silver and nickel. This method has high precision.

Eddy Current Thickness Measurement method

It is suitable for measuring the thickness of non-conductive layer on conductive metal. This method is less accurate than magnetic thickness measurement.

Ultrasonic thickness Measurement method

At present, there is no such way to measure the thickness of coating, foreign single manufacturers have such instruments, the application of multi-layer coating thickness measurement or the above two methods are unable to measure the occasion. However, the price is usually not expensive measurement precision.
