1、Simple Operation: Only zero adjustment is required without calibration, the only button operation is extremely simple, and the measurement is completed in 0.5 seconds. 2、Multifunction: The instrument has the recognition function of iron powder putty layer and iron galvanized layer, and adopts 3 color backlight indication. The wear resistance of the carbuncle ​​probe ensures long term effective use of the instrument. 3、Iron Aluminum Dual Purpose Probe: Automatically identify iron, aluminum and non metallic substrates, and can be quickly and automatically converted. "Fe" "NFe" "Fe/NFe" three measurement modes can be set. 4、Applicability: It can measure the thickness of non magnetic coating layers on magnetic metal substrates such as steel, and the thickness of non conductive coating layers on non magnetic metal substrates such as copper and aluminum. 5、Digital Probe Technology: Using advanced digital probe technology, digital signal processing is directly completed on the probe, the probe is not easily disturbed and provides excellent test accuracy. Even if temperature changes do not affect the measurement, the reading remains stable to ensure very good repeatability throughout the measurement.
