Features: It has the ability to measure the thickness of non magnetic coating (such as paint) on magnetic materials such as steel/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.
