AT-220, AT-230, AT-240 these instruments use magnetic thickness measurement method, can detect the thickness of non-magnetic coating (such as: zinc, aluminum, chromium, copper, rubber, paint etc.) on magnetic metal matrix iron (such as: iron, steel, alloys and hard-magnetic steel, etc.) without damage. AT-220F, AT-230F these instruments use vortex thickness measurement method, can detect the thickness of non-conductive coating (such as: rubber, paint, plastic, anodic oxide film, etc) on non-magnetic metal matrix iron. (Such as: copper, aluminum, zinc, tin, etc.) without damage. AT-260, AT-280 these instruments use both magnetic and vortex thickness measurement methods, can detect the thickness of non-magnetic coating (such as: zinc, aluminum, chromium, copper, rubber, paint etc.) on magnetic metal matrix iron (such as: iron, steel, alloys and hard-magnetic steel, etc.) and the thickness of non-conductive coating (such as: rubber, paint, plastic, anodic oxide film, etc) on non-magnetic metal matrix iron. (Such as: copper, aluminum, zinc, tin, etc.) without damage. This instrument is widely used in the field of manufacturing, metal processing industry, chemical industry, commodity inspection, etc detection fields. It's Professional essential instrument for material protection. http: //www.shcaliper.com/
