ABSTRACT:
A readily portable, hand-held coating thickness measuring device which utilizes a pin to penetrate a coating and a gauge to accurately determine the thickness of the coating based on the degree of penetration is disclosed. The pin is formed at a tip of an elongated rod that can reciprocate relative to the body of the device is response to manually pivoting a trigger member. The device is particularly adapted to determine the thickness of coatings applied to metal surfaces. For this purpose, the device includes a signalling assembly to visually indicate to the user when the coating has been fully penetrated and the gauge should be read.
