1. Introduction

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.

1. 1 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.
