The TT130 ultrasonic Thickness Gauge has a display resolution of 0.01, which can measure more precise workpieces than the TT100 model, with accurate measurement and automatic zero point calibration. Beijing Times Ultrasonic Thickness Gauge Series is a collection of contemporary science and technology electronic technology and measurement technology in one, professional non-destructive testing instruments, the use of microcomputer analysis, processing, display, the use of highly optimized measurement circuit, with high measurement accuracy, wide range, easy operation, stable work and other specific. This principle can be used to measure all kinds of materials that can make ultrasonic waves propagate inside at a certain speed, such as metals, plastics, ceramics, glass, etc., and can accurately measure various plates and processed parts.

When the ultrasonic pulse emitted by the probe reaches the material interface through the measured object, the pulse is reflected back to the probe, and the thickness of the measured material is determined by accurately measuring the time of ultrasonic wave propagation in the material.
