Principle of Measurement
Magnetic Principle(Fe):Measure the thickness of non-magnetic coatings (such as paint layer, various anticorrosive coating, coating, powder spraying, plastic, rubber, synthetic materials, phosphating layer, chromium, zinc, lead, aluminum, tin, cadmium, etc.) on ferromagnetic metal substrates.
Eddy Current Principle (NFe) : Measure the thickness of all non-conductive coatings (such as rot coating, coating, powder coating, plastic, rubber, synthetic materials, oxide film, phosphating film) on non-ferromagnetic substrates like copper, aluminum and stainless steel.
