GM130 Digital LCD Ultrasonic Thickness Gauge Tester Depth Gauge + Sound Velocity Meter Range

Introduction 

This ultrasonic thickness gauge is an intelligent handhold 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. The material that conduct and reflect constant sonic velocity, this product is to be applicable to used. 
a. Scope of application This unit is not suitable for cast iron due to its big crystalloid composition. 
b. How it work This unit is comprised of transimtting circuit, receiving circuit, Hi-frequency oscillator, counter, central unit processor, keypad, and moniter etc., adopting ultrasonic pulse reflect principle. Similar to light-wave measure principal, the sonic pulse occurs form the unit travels through the material being measured till reach the interface and reflects back to determine the thickness of the target material.

Functions: 
1. Auto calibration to assure the accuracy 
2. Auto linear compensation: this advanced software program enhances the precision by correcting the non-linear accuracy of transducer 
3. Make a quick adjustment for the sound velocity / thickness, and a quick recall to the stored data 
4. Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not 
5. 10 thickness measurement storage and recall function available, which facilitates the height work or working in wild area. 
6. Sound velocity measurement 
7. 12 sound velocity for different material which also adjustable
