TT150 Ultrasonic Thickness Gauge

TT150 Ultrasonic Thickness Gauge



The principle of Ultrasonic Thickness Gauge is ultrasonic pulse reflection. The pulse was reflected back to the probe when the ultrasonic pulse sent by the probe reaches the material interface through the tested object. We can get the thickness of the measured material based on the accurate time that the ultrasonic transits in the material. Time Ultrasonic Thickness Gauge series are non-destructive testing instrument integrated with modern scientific electronic and measuring technology. They are equipped with microcomputers that can analyze, handle and display the current data. Furthermore, they are integrated with highly optimized measuring circuit, which makes them have the advantage of high measurement accuracy, wide measurement range, being easy to operate, stable working and so on. TT150 is an updated version of TT100, and it was deeply loved by the users with the brand new appearance and oil-proof, water-proof case
