Feature: 1. Ultrasonic Thickness Gauge: The high accuracy thickness gauge allows you to measure the thickness of metal (such as steel, aluminum, copper, etc.), plastic, ceramics, glass, and other homogeneous materials through ultrasonic principle. 2. Measurement Range: The measurement range of this ultrasonic thickness gauge is 1300mm (steel), with a minimum resolution of 0.01mm (1.0099.99mm) and 0.1mm (100300mm), suitable for industrial applications. 3. Sound Velocity Setting: Use a block and independent sound velocity settings for calibration, with a velocity adjustment range of 10009999m/s. Equipped with a fast microprocessor for convenient and accurate measurement. 4. Convenient and Practical: This is a highly accurate and compact thickness measuring instrument that can be widely applied in manufacturing, metal processing, commercial inspection, and all other testing fields. 5. Versatile Use: This ultrasonic thickness tester can be applied to determine the average thickness of production equipment pipelines and pressure vessels, as well as to find the degree of erosion of various parts in use.
