This coating thickness gauge adapts the principles of electromagnetic induction and magnetically induced EDD current. It can measure the thickness of non-metallic coatings on the metal surface. Press the button to select magnetic metal or non-magnetic metal. It is an ideal instrument in manufacturing, machinery, chemical and commodity control industries, especially in automobile trade. Features: The measuring range is 01,25mm non-metal coating on metal surface. Mm/mil two units available and switchable. Digital LCD display and data storage for easy and clear reading. It will turn off automatically within 1 minute without any operation. Press the ON button to turn on, then press Fe/NFE to select the type of metal and finally press Zero to select the unit. Fe stands for metal magnetic panel, while NFE stands for non-magnetic metal panel. Ma advantages of easy operation, fast measurement, safe use and portability. Instructions for use: Press and turn on tester to start the measurement. The thickness of the coating on the metal surface will be displayed on the LCD screen. Quickly remove it from the test surface. The measured value will be saved on the LCD screen.
