LS215 ultrasonic thickness gauge adopts the pulse echo measurement principle to perform nondestructive testing on steel, aluminum, copper, plastics, ceramics, glass, and other sound-conductive materials. With a display resolution up to 0.01 mm, the LS215 meets the accuracy requirements verified by the national metrology institute. Four probes are available—standard, micro-diameter, coarse-crystal, and high-temperature—which can be freely selected based on application needs.

Application

Suitable for measuring the thickness of metal plates, steel parts, pipes, ceramics, plastics, glass and any other material that conducts ultrasonic waves.

Note: For accurate results, the rear surface of the test piece must be parallel or coaxial with the test surface. For curved samples, ensure the split surface of the probe is perpendicular to the curvature axis.
