Ultrasonic thickness gauge, GM130 Digital ultrasonic thickness gauge steel width test monitor, Coupling status indication

General Description

The GM130 ultrasonic thickness gauge is a digital tool designed to measure the thickness of materials, particularly steel. It offers high accuracy thanks to its automatic calibration and the ability to measure the speed of sound for different materials. This device is equipped with a backlit display and clear coupling status indicators, as well as a thickness alarm and an automatic shut-off function.
