The LH-373 is a coating thickness tester capable of measuring the thickness of insulating coatings on non-ferrous metal substrates. While having the same functions as the LE-373, which measures coatings on ferrous metal substrates, it is also capable of precisely measuring comparatively thin coatings, such as alumite.
