State of the art, digital ultrasonic thickness gauge is capable of reading wall thickness thru coatings and paint without affecting the measurement and is packed with the most popular features including basic measurement, Scanning Capabilities, Adjustable Sound Velocity, and extended memory capabilities. This dynamic ultrasonic thickness gauge is designed to measure the thickness of metallic and non-metallic materials such as steel, aluminum, titanium, plastics, ceramics, glass and any other good ultrasonic wave conductor as long as it has parallel top and bottom surfaces. The UTG-2600 ultrasonic thickness gauge will accurately display readings in either inch or millimeter after a simple calibration to a known thickness or sound velocity.
