The UM series ultrasonic thickness gauge developed and produced by Yushi Instruments adopts the principle of ultrasonic measurement and is an ultra-small measuring instrument. It can measure quickly and accurately without destruction. The instrument can be widely used in manufacturing, metal processing industry, chemical industry, commodity inspection industry and other inspection fields. It is suitable for measuring the thickness of various materials which can make ultrasonic waves propagate inside at a constant speed and can be reflected from its undersurface. In addition to measure various kinds of plates and processed parts accurately, it can also monitor various kinds of pipelines and pressure vessels in production equipment to get the remaining thickness after corrosion.
