Features Magnetic induction and Eddy Current dual principle sample: the thickness gauge is mainly used to measure the non-conductive coating on the metal surface and the non-ferro magnetic coating on ferro magnetic metal. The metal ub strat to be tested can be automatically decorated identically and the thickness of the coating can be automatically calculated by simply placing it on the surface to be tested. FOR A VARIETY OF APPLICATIONS: Utility multifunction meters are ideal for checking the thickness of car paints, e.g. Used car paints, powder coatings, anodised aluminium, bathroom accessories, bicycle frames, stadium seats, outdoor sheds, furniture, swings, cabinets and lockers as well as computers, household appliances and toys. For the used car market: a painted car visually conceals everything that does not indicate that it had a serious accident. When buying a used car, check the car paint to make sure it has approximately the same thickness on all sheets. This high precision coating thickness gauge is ideal for you. Highly accurate coating thickness tester: With a measuring accuracy of ± 3% + 1 µM, a measuring range of 0 to 2000 µm and a simple and fast zero calibration, the coating or coating thickness can be measured quickly and accurately on almost all metal surfaces. EASY TO READ DISPLAY: The colour depth meter with large backlit display shows metal type, operating mode, quantity, battery status and readings in µm, mm and mil units.
