1. GB/T 4956-1985 non-magnetic coating thickness measurement on magnetic metal substrate, Magnetic Method
2. Speaker beep while operating.
3. Power-off automatically when idle; manually power-off available.
Product description: This device is currently widely used in manufacturing, metal processing industry, chemical industry, commodity inspection and testing fields, and is essential for material protection major.The device uses magnetic thickness measurement method, which non-destructively measures thickness of non-magnetic coating (such as: aluminum, chromium, copper, enamel, rubber, paint, etc.) on magnetic metal substrates (such as steel, iron, alloy and hard magnetic steel, etc.).
Magnetic Method (F-type probe)
When the probe contacts the cover layer, the probe and magnetic substrate forms a closed magnetic circuit; Due to the presence of non-magnetic coating, magnetic resistance changes. The thickness of the cover layer can be derived by measuring the change.
