Ultrasonic Thickness Gauge Certificate Calibration Smart Sensor AS840

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

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. Use and keys to 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 is available,
6. which facilitates the height work or working in wild area.
7. Sound velocity measurement
8. 12 sound velocity for different material
9. Low battery indication
10. Auto power off
11. More than 10000 times long lift keys.
12. Manual power off
