3812 Ultrasonic Thickness Gage 67668

Ultrasonic Thickness Gage is a menu driven, multifunctional tester with basic measurement capabilities. This gage is designed to measure the thickness of metallic and non-metallic materials such as aluminum, titanium, plastics, ceramics, glass and any other good ultrasonic wave conductor, as long as it has parallel top and bottom surfaces. The 3812 will accurately display readings in either inch or millimeter after a simple calibration to a known thickness or sound velocity.
