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: 2.0 inches large segment screen, 180 degree screen flip for different views angle during measuring process. Automatic detecting the metal properties and display on the LCD, symbol Fe for magnetic substrate and NFe for non-magnetic substrate. Simple operation, directly attach to the coating and on screen shows the property and thickness. Provide Zero and Multi-spots calibration, calibrating reliably and rapidly. Saving the measured data up to 30 sets, power-off will not obliterate data. Warning function of upper/lower limits. 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.
