RUT5000A is a new type of handheld high-precision digital ultrasonic
thickness gauge with A/B scanning. It adopts the principle of ultrasonic
thickness measurement based on pulse reflection. It is suitable for the
measurement of material thickness that can make ultrasonic wave propagate in it
at a constant speed and get the reflection from its back. The measurement
resolution is 0.001mm and the measurement range is as thin as 0.15mm (steel).
    This product can accurately measure plates and processed parts. On the
other hand, it can monitor the thinning degree of pipes and pressure vessels in
production equipment after corrosion during use. It can be used in petroleum,
chemical industry, metallurgy, shipbuilding, aerospace, energy and other
    This product complies with the following standards: Calibration
Specification for ultrasonic thickness gauge (JJF 1126-2004).

 Applicable Materials
    It is suitable for measuring the thickness of metals (such as steel, cast
iron, aluminum, copper, etc.), plastics, ceramics, glass, resin, glass fiber
and other good ultrasonic conductors.
 Basic Principles

The principle of ultrasonic thickness measurement is similar to that of light wave measurement. The ultrasonic pulse emitted by the probe reaches the measured object and propagates in the object. When it reaches the material interface, it is reflected back to the probe. The thickness of the measured material is determined by accurately measuring the time of ultrasonic propagation in the material.
