The Phase II PTG-3525 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 gage, you can easily detect the thickness of non-magnetic coating on a magnetic substrate (ferrous) or an insulating coating on a non-magnetic conductive substrate (non-ferrous) utilizing our version that comes with 2-external probes. The Phase II PTG3525 can be used in many areas of industry including manufacturing, general engineering, commercial inspection, etc.
