Features: It has the ability to measure the thickness of non magnetic coating (such as paint) on magnetic materials such as steel or iron, as well as the thickness of coating (such as paint) on non magnetic materials such as aluminum. Built in precision-probe, lithiums battery charging. Automatically detect substrate properties and detect coating thickness through electromagnetic induction and eddy-current effects. This instrument can non-destructive measure the thickness of the coating, with fast speed and high accuracy. Widely used in manufacturing, chemicals industry, automotive and other testing fields.
