Ultrasonic thickness gauge employs the measuring principle of ultrasonic. The ultrasonic thickness gauge is applicable to measure the thickness of all kinds of material, through which the ultrasonic wave can propagate at a constant speed and can get a reflection from the back. The ultrasonic thickness gauge can be employed in a variety of plates and all kinds of machining parts for accurate measurement. Another important function of the ultrasonic thickness gauge takes care of all kinds of pipelines and pressure vessels used in the production equipment, monitoring their degree of corroded thinning during the using process. The ultrasonic thickness gauge is widely used in petroleum, chemical industry, metallurgy, shipbuilding, aviation, aerospace and other fields. We use the latest high performance and low power consumption microprocessor technology to produce ultrasonic thickness gauge, easy and convenient to use.
