Handheld high-precision ultrasonic thickness gauge with numerical display and A/B scanning function. Using the principle of pulse reflection ultrasonic thickness measurement, it is suitable for measuring the thickness of materials that can propagate ultrasonic waves at a constant speed and obtain reflection from their back. The measurement resolution reaches 0.001mm, and the measurement range is as thin as 0.14mm (steel), which can effectively penetrate coating interference. This product can be applied in various fields such as petroleum, chemical, metallurgy, shipbuilding, aerospace, energy, etc. Compliant with the standard "Calibration Specification for Ultrasonic Thickness Gauge" JJF1126-2004

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