Product Description


   MT130 Ultrasonic Thickness Gauge  is an intelligent handheld product, which adopts ultrasonic measuring principle and is controlled by micro processor, provides quick and precise measurement of thickness for most of industrial material. This unit is widely used in various precise measurement for different hardware/parts in industrial realm; one of its important application is to monitor the level of thickness-decreasing during operation of various and pressure container. Diffusely applied in manufacture fields, metal processing, and commercial inspection.


  This unit is suitable for measuring materials that are good ultrasonic conductor such as metal, plastic, ceramic, glass etc., as long as the measured part in two parallel surfaces for measurement of thickness, but not suitable for cast iron due to its big crystalloid composition.
