Easy Operation: Built-in magnetic induction and vortex double principle probe, can automatically identify the measured metal substrate, only need to be placed on the measured surface, can automatically calculate the thickness of the coating. Digital LCD Display: Digital display with backlight, support statistical data display, average, minimum, maximum and number. This instrument supports up to 50 data to carry on the statistics, when reaches 50, the latest data will replace the oldest data, the statistical value will be updated automatically. Three Probe Modes: With three probe modes of automatic (AUTO) mode, magnetic induction (F) mode and vortex (NFE) mode, you can switch depending on your needs. Unit Switching Function: Press to switch the units between -um, millimeter mm, and Mill mils. Calibration: In order to improve the test accuracy, it is suggested that the instrument should be calibrated, to higher accuracy. Multifunctional Design: Equipped with battery power indicating and 3 minutes no operation automatic shutoff function, and support turn on and off the backlight. Standard Aluminum Film: Comes with aluminum sheet and 6pcs calibration films, with different thickness of 0.05mm, 0.25mm, 0.10mm, 0.50mm, 1.00mm and 2.00mm to meet your demands. Measurement Object: The tester is used for non-destructive measurement of coating and paint thickness, fast and accurate. It is mainly used to measure the thickness of non-conductive coating on metal surface, as well as the thickness of non-ferromagnetic coating on ferromagnetic metal (such as iron, nickel, cobalt, etc.), such as paint thickness on automobile surface, coating thickness of metal parts and so on. Wide Applications: It is widely used in manufacturing, metal processing industry, chemical industry, commercial inspection, etc. It can also workstably in the laboratory, workshop and other fields.
