| High Light | High Precision Ultrasonic Thickness Gauge ，0.001mm Resolution Digital Thickness Gauge ，A/B Scanning Thickness Measurement Device | ||
TM290 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 fields.
This product complies with the following standards: Calibration Specification for ultrasonic thickness gauge (JJF 1126-2004).
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.
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.
Note: the company reserves the right to make technical modifications without prior notice.
