MEWOI-ST220B ultrasonic thickness gauge is used for measuring the thickness according to the principle of ultrasonic pulse reflection, and when the ultrasonic pulse transmitted by the probe reaches the material sub-interface through the object to be measured, the pulse is reflected back to the probe, The thickness of the measured material is determined by accurately measuring the time of propagation of the ultrasonic waves in the material.
MEWOI-ST220B ultrasonic thickness gauge series is a kind of advanced non-destructive testing instrument, which integrates modern science and technology electronic technology and measurement technology. It adopts microcomputer to analyze, process and display the data in time, and adopts highly optimized measuring circuit. It has the characteristics of high precision, wide range, simple operation, stable and reliable operation. All kinds of materials, such as metals, plastics, ceramics, glass, which can make ultrasonic wave propagate at a constant speed, can be measured by this principle. It is widely used in petroleum, chemical, metallurgy, shipbuilding, aviation, aerospace and other fields.
