The ultrasonic thickness gauge is the thickness testing equipment that can measure the thickness of various materials such as metal materials, high temperature pipes, pipes, steel plates, aluminum plates, plastics, iron pipes, PVC pipes, glass, etc. It can be widely applied for these material testing in the fields like manufacturing, metal processing, chemical industry, commodity inspection, etc. This series of ultrasonic thickness gauge is extremely suitable for measuring the thickness loss of pipes and pressure vessels after corrosion. The ultrasonic thickness gauge is a most suitable instrument for material protection.

Tips: Measurement Method of Ultrasound Thickness Gauge

1. Single-point measurement method
It means that the ultrasound thickness gauge is used to measure any point of the measured material with a probe, and the display value is the thickness value.

2. Two-point measurement method
The ultrasound thickness meter is used to make two measurement at the same point of the measured material with a probe. In the second measurement, the probe's split surface is 90 degrees, and the smaller value in the two measurements is the thickness value.

3. Multi-point measurement method
When the measurement value is unstable, takes a measuring point as the center and makes multiple measurements in a circle with a diameter of about 30 mm. The minimum value is the thickness value.
