Small DiaMeter Thickness Gauge

The small-diameter thickness gauge utilizes the principle of ultrasonic waves propagating and reflecting within materials. By placing the probe in contact with the outer wall of the pipe, it measures the round-trip time of the ultrasonic waves to calculate the wall thickness. It is used to inspect the wall thickness of pipes, containers, and other narrow areas, as well as to detect corrosion or wear in industrial maintenance and quality control.
Selection
When selecting a small-diameter thickness gauge, considerations include ensuring the measurement range covers the dimensions of the pipes to be tested, the accuracy meets inspection requirements, the probe size accommodates pipe curvature, the device has data storage capabilities, it is user-friendly for on-site operations, and its environmental durability aligns with working conditions.
