CTG-A Coating Thickness Gauge

Our Model CTG-A, Portable Coating Thickness Gauge (CTG), is designed on principle of electromagnetic induction. The CTG has adopted the monolithic microcomputer as the control unit. It is used to measure the thickness of the coating over on the magnetic substrates, e.g., to measure the thickness of a chromium coating or a painted coating on an iron substrate.
