Description
Overview
GAOTek portable digital coating thickness tester is a battery-powered measuring instrument that adopts the principle of magnetic induction and eddy current. It is suitable for the laboratory and for use in harsh field conditions. The F probes measure the thickness of non-magnetic materials (e.g., paint, plastic, porcelain enamel, etc.) on magnetic materials (e.g., iron, nickel, etc.) often used to measure the thickness of galvanizing layer, lacquer layer, porcelain enamel layer, phosphide layer, copper tile, aluminum tile, paper etc. the N probes measure the thickness of non-magnetic coatings on non-magnetic metals. It is used on anodizing, varnish, paint, enamel, plastic coatings, powder etc. applied to aluminum, brass, on-magnetic stainless steel etc.
Features
