    Product Description

    PTG-3500 Coating Thickness Gage

    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 nonmagnetic 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.
