LS221 coating thickness gauge is also called coating thickness meter and paint thickness meter. It is a professional instrument for measuring the thickness of metal surface coatings. The host and the probe adopt a separate design, which is convenient for viewing data while testing under complex test conditions. It can be used in the laboratory and engineering field.

Hall effect: can be used for the measurement of non-ferromagnetic coatings on ferromagnetic metal substrates.
Eddy current: can be used for the measurement of non-conductive coatings on non-magnetic metal substrates.
