Coating Thickness Gauge

Model No. PTG-4200

Coating thickness measurement with color Flip Display!


The PHASE II PTG-4200 coating thickness gauge can perform two different methods of calculating thickness measurement by utilizing the characteristics of both eddy current and magnetic induction.


Testing performance is both non-destructive and extremely accurate.


With this state of the art coating thickness gauge, you can easily detect the coating thickness of nonmagnetic coating on a magnetic substrate (ferrous) or an insulating coating on a non-magnetic conductive substrate (non-ferrous) utilizing our auto-detect, integrated probe


The PTG-4200 coating thickness gauge can be used in many areas of industry including automotive auctions, manufacturing, general engineering, commercial inspection, etc.
