Coating Thickness Gauge

 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/
