This coating 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, with the function of backlight large LCD display and detecting the metal properties automatically. This Coating Thickness Tester is perfect for manufacturing company, metal machinery industry, chemical industry and commodity inspection especially automobile trading. Features: Quickly measure the thickness of paint coating with wider measuring range: 0-1700um/0～67.8mil and 3 simple one-hand operation buttons. Automatic detecting the metal properties and display on the LCD, symbol Fe for magnetic substrate and NFe for non-magnetic substrate. Automatically power on and measure with μm/mil units switchable and V-Groove on probe for small cylindrical parts. Convenient auto calibration modes: automatic calibration according to 5 different calibration plates of 0, 50, 100, 250, 500. Automatic correction function to prevent misuse calibration. With Max, Min, Average value display. 180 degree screen flip for easy data reading. Large LCD display with max 20 store data and bright backlight, easy for you to read the results clearly. "Beep" sound when measurement or calibration is completed. Portable and streamline form design with special handheld anti-skid treatment, light weight, small and fitted size for your palm. Widely used in manufacturing industry, metal-processing industry, chemical industry, commodity inspection area, and also able to work steadily in the laboratory, workshop and outdoor.
