LH-373

LH-373 coating thickness tester

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.

Applications
Insulating coating on non-ferrous metal substrate
Functions
16 types of internal functions
