1, Convenience: It is a very precise and compact instrument used to quickly and accurately measure the thickness of the coating or electroplating on all kinds of metal surfaces. Can be calculated automatically by placing it only on the surface to be tested. 2, Accuracy: Zero calibration To improve the testing accuracy, it is recommended to calibrate the instrument to zero. Press and hold until you hear a dripping sound and the zero calibration on the screen starts flashing. 3, easy to use: the probe is placed vertically and quickly on the substrate surface uncoated to examine. After hearing the dripping sound, the screen displays O, and the probe can be lifted at least 2cm from the substrate, that is, back to zero once. 4 , Powerful: It measures paint thickness, but more importantly, this paint coating thickness tester can detect problems that you may not be able to see with the naked eye. 5, widely used: This device can be used to determine the average thickness of paint on the car body, used in manufacturing, metal processing, chemical industry, commodity inspection, laboratories, workshops.
