TG-5700 Big Measurement Range High-Precision Ultrasonic Thickness Gauge
TG-5700 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.
