Digital Coating Ticknes 0-1300um Gauge Tester Meter HT-128

HT-128 digital coating thickness meter gauge painting paint thickness tester 0--1300um 
Product introduction:
The product adopts two types of principle of electro-magnetic induction and eddy current effect. The electro-magnetic induction principle is used to measure thickness of non magnetic coating and galvanization layer (such as paint) on magnetic conductive metal substrate (such as iron). The principle of eddy current effect is used to measure thickness of non conductive coating (such as paint) on non-magnetic conductive metal substrate (such as aluminum).
