86215 Ultrasonic Thickness Gauge
Measurement from 1–320 mm with 0.01 mm display resolution
Nondestructive measurement of metal pipes, steel plates and plastics
Compatible with 4 interchangeable probes for broader applications
High accuracy, compliant with metrology verification requirements
999 data groups for secure data storage
86215 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 86215 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.
