●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).

Main Function Characteristics

● Large 3.5-inch color TFT-LCD display with 320x240 high definition (QVGA) resolution;

● It has a variety of calibration methods, supports one-point calibration, multi-point calibration and manual calibration modes, and can calibrate sound velocity and probe zero position at the same time; It supports v-path correction of double crystal probe.

● It supports the conversion of metric and British system; It can switch between millimeter and inch units;

● It supports Chinese and English display;

 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.
