Mini LCD Digital Display Paint Thickness Tester Car Coating Measuring Gauge Testing Instrument This coating thickness gauge adapts principles of electromagnetic induction and magnetic induced EDD current. It can measure the thickness of non-metal coatings on metal surface. Press the button to select magnetic metal or non-magnetic metal. It is an ideal instrument in manufacture, metal machine industry, chemical industry and commodity inspection, especially in automobile trading. Features: Measuring range is 0~1.25mm nonmetal coating on metal surface. Mm/mil two units available and switchable. LCD digital display and data hold for easy and clear reading. It will automatically power off in 1 min without any operation. Press ON button to power on, then press Fe/NFE to choose the metal type and finally press Zero for unit. Fe means magnetic metal panel while NFE stands for non-magnetic metal panel. It has the advantages of easy operation, rapid measurement, safe usage and portability. Instructions for Use: Press and turn on the tester to start measuring. The thickness of the coating on the metal surface will be displayed on the LCD screen. Quickly remove it from the tested surface. The measured value will be saved on the LCD screen.
