Ultrasonic Tester / Ultrasonic Testing | PCE Instruments

Ultrasonic testing (UT) is a form of non-destructive testing (NDT) that uses high-frequency sound waves to measure the thickness or hardness of a material. Ultrasonic tests often are performed to assess corrosion on pipes, valves and steel or aluminum constructions. An ultrasonic tester also is used to detect flaws such as cracks and leaks.
