Features 1、The thickness gauge is used to measure the thickness of the plated and coated sheet on metal, e.g. paint/enamel/ chrome on steel, paint and anodizing coating on aluminum/copper. 2、The measuring range is stable and accurate. 3、The gauge takes the accurate integrated probe, and uses principles of electro-magnetic induction and the eddy current effect, which automatically detects the attribute of substrates. 4、The gauge is designed for non-destructively measuring the thickness of coating and painting. 5、It is practical for material surface treatments and widely used in manufacturing industry, metal-processing industry, commodity inspection area, and also able to work steadily in the laboratory, workshop and outdoor.
