FNIRSI® CTG-20 Car Paint Coating Thickness Gauge

CTG-20 is a coating thickness gauge used to measure the thickness of electroplated coatings or coatings on metal surfaces. 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, lithium 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, chemical industry, automotive and other testing fields.
