Dry Film Coating Thickness Meter Painting Thickness Tester 0.0-2000um LS220H. LS220H is an integrated high-precision coating thickness gauge, which combines the Hall effect and eddy current thickness measurement principles. This gauge can be used for coating thickness on various metal substrates. There are only four types of ferromagnetic metal elements at room temperature: iron, cobalt, nickel, and gadolinium. Common non-ferromagnetic metals: copper, aluminum, magnesium, zinc, chromium, etc. 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. Ferromagnetic materials: Iron, cobalt, nickel, gadolinium. Galvanized iron copper plating. Iron spray paint 2. Iron spray powder coating. Ferromagnetic material: Iron, cobalt, nickel and gadolinium. Non-ferromagnetic metal: Copper, aluminum, magnesium, zinc, etc. Anodized ; aluminum surface 2.
