Description
Working Principle
AUTOOL TG501 car paint thickness tester is a magnetic coating thickness gauge that uses the principle of magnetic induction to determine the coating thickness by measuring the change in magnetic flux. When the probe comes into contact with the coating, a closed magnetic circuit is formed between the probe and the magnetic substrate. The presence of a non-magnetic coating changes the reluctance of the magnetic circuit (the greater the reluctance, the smaller the magnetic flux). The thicker the coating, the greater the reluctance and the smaller the magnetic flux. By measuring the change in magnetic flux, the instrument can calculate the thickness of the coating.
