Compact Designed Coating Thickness Gauge is designed for measuring coatings on ferrous [magnetic] as well as non-ferrous materials. The Gauge is provided with FD-Electromagnetic induction probe that measures non-magnetic [metallic or non-metallic] coatings on ferrous [magnetic] base materials. The Coating Thickness Gauge comes with ND-eddy-current probe measures non-conducting [non-metallic] coatings on conducting base materials [non-ferrous metallic]. Compact Designed Coating Thickness Gauge is available in a rugged construction with custom liquid crystal display and key pad controls.
