The Phase II PTG-3500 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 thickness gauge, you can easily detect the thickness of a non-magnetic coating on a magnetic substrate (ferrous) or an insulating coating on a non-magnetic conductive substrate (non-ferrous) utilizing either an integrated probe or our version that comes with 1 auto-detect external probe. The Phase II PTG-3500 can be used in many areas of industry including manufacturing, general engineering, commercial inspection, etc.
