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. Ferromagnetic material: Iron, cobalt, nickel and gadolinium.
Non-ferromagnetic metal: Copper, aluminum, magnesium, zinc, etc. Fe: Hall Effect / NFe: Eddy current.
