EC-370 thickness gauge has a built-in magnetic induction and eddies current effect integrated probe, which can non-destructively measure the thickness of non-conductive coatings on metal surfaces and non-ferromagnetic metal coatings on ferromagnetic metals (such as iron, nickel, cobalt). Specific uses include measuring the thickness of the paint or galvanized layer on the surface of iron and stainless steel and the thickness of the paint or plastic film on the surface of aluminum and copper.
