Product Introduction
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. TT120 Ultrasonic Thickness Gauge can fix the sound velocity as 5900m/s( the sound velocity of steel), which makes is suitable for the exact checking of all kinds of boards and processing parts. And on the basis of TT110, it is equipped with the function of testing high temperature steel, and the highest temperature can reach 300°C.
