SMART SENSOR Ultrasonic Thickness Gauge This unit 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.

Scope of application
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. This unit is not suitable for cast iron
due to its big crystalloid composition.
