Description:

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-de-creasing 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.

Features:

Auto calibration to assure the accuracy.
Auto linear compensation: this advanced software progr- am enhances the precision by correcting the non-linear accuracy of transducer.
Use and keys to make a quick adjustment for the so- und velocity /thickness,and a quick recall to the stored data.
Coupling status indication: Observing the coupling icon to learn if the coupling is accomplished or not.
10 thickness measurement storage and recall function available, which facilitates the height work or working in wild area.
Sound velocity measurement: With a given thickness by a sample hardware to measure the sound velocity, which avoid the further conversion or consultation of the table.
12 sound velocity for different material which also adjus- table.
Low battery indication
Auto power off mode designed to conserve battery life. More than 10000 times long lift keys.
The unit has a special memory that retains all of its setting even when the power is off.
