LS212 ultrasonic thickness gauge is easy to operate and uses the principle of ultrasonic pulse reflection to test the thickness of materials. The instrument can be equipped with four types of probes: standard probe, micro-diameter probe, coarse crystal probe and high temperature probe, and is professionally used for thickness measurement of metals (such as steel, aluminum, copper, etc.), plastics, ceramics, glass, fiberglass and other materials that can transmit ultrasonic waves. The instrument adopts professional chip design of timing, resolution up to 0.001mm.
