• The model LE-373 electromagnetic coating thickness tester is designed to measure the thickness of non-magnetic
coatings such as paint or plating on magnetic metal substrates (iron or steel).
• The model LH-373 Eddy Current coating thickness tester is designed to measure the thickness of insulating coatings
such as alumite or paint on non-magnetic metal substrates (such as aluminum or copper, etc.).
• The model LZ-373 dual-type coating thickness tester is designed to measure the thickness of either non-magnetic or
insulating coatings on either magnetic or non-magnetic metal substrates.
• A Beryllium-copper calibration foil is required in order to
measure the thickness of plating coatings.
