TT230 coating thickness tester Coating thickness gauge
This instrument is a super small measuring instrument, it can fast, no damage, precision of non magnetic metal non conductive cover layer thickness measurement. Can be widely used in manufacturing industry, metal processing industry, chemical industry, commodity inspection and testing field. Due to the small size of the apparatus, probe and instrument integration, especially suitable for field engineering measurement.
This instrument meets the following criteria:
GB/T 4957 - 1985 of non magnetic metal non conductive cover layer thickness measurement of eddy currentmethod
JB/T 8393 - 1996 magnetic and eddy current measuring instrument for coating thickness
JJG 818 - 93 "eddy current thickness measuring instrument"
Function characteristics:
This instrument adopts eddy current thickness method,can be nondestructively measuring non-conductive coverlayer thickness of the non magnetic metal (such ascopper, aluminum, zinc, tin and other substrate enamel,rubber, paint coatings)
