GM-100 DIGITAL ULTRASONIC THICKNESS METER Tester Gauge Velocity 1.2~225mm Metal. The Digital Ultrasonic Thickness Gauge is an intelligent that adopts ultrasonic measuring principle. Controlled by micro processor, offers immediate and precise measurement of thickness for most of industrial material. The measurement range of 1.20~225.00mm combined with ultrasonic wave velocity measurement function of 1000~9999m/s provides accurate measurement readings. Widely used in various precise measurements for different hardware/parts in industrial realm. One of its important applications is to monitor the level decreasing thickness during operation of various and pressure container. Diffusely applied in manufacture fields, metal processing as well as commercial inspection and can be applied for materials that conduct and reflect constant sonic velocity.
