Test function: This thickness gauge is used to measure the thickness of metal plating and coated plates, such as paint/enamel/chrome on steel, varnish and anodized coating on aluminum/copper. Measuring scale: The measuring scale is 0-2000um. With the built-in magnetic induction probe and dual eddy current principle, it can automatically identify the metal substrate to be tested. Precise and precise: The thickness gauge can automatically accurately detect substrate characteristics. Convenient to use: No matter concave, rough or convex, all can measure the thickness of coatings non-destructively. Widely used: The thickness gauge is an indispensable tool for material processing. It is widely used in manufacturing industry, metal processing industry, chemical industry and commodity inspection field, and can also be used continuously in laboratories, workshops and outdoors. Product size: 120mm*45mm*23mm Accessories: 1pc thickness gauge + manual + calibration sheet, white carton packaging.
