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.
