Test Function: This thickness gauge is used to measure the thickness of metal plating and coated plates, such as paint/enamel/chrome on steel, paint and anodize coating on aluminum / copper. Measurement scale: The measurement scale is 0-2000um. With the built-in magnetic induction probe and dual eddy current principle, it can automatically identify the metal substrate under test. Accurate and Accurate: The thickness gauge can automatically detect the properties of the substrate with precision. Convenient to use: No matter concave, rough or convex, it can all measure the thickness of coatings non-destructively. Widely used: the thickness gauge Thickness is an indispensable tool for material processing. It is widely used in manufacturing industry, metal processing industry, chemical industry, commodity inspection field, and it can also work continuously in labs, workshops and at home. 'outside.
