Digital calibre Ultrasonic Thickness Gauge Tester paint-coating-thickness-gauge Depth Gauge + Sound Velocity Meter 1.2~225mm

This ultrasonic thickness gauge 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 manufacturing fields, metal processing, and commercial inspection.
Features & 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 is also adjustable .
8. More than 10000 times long life keys.
9. Largr LCD display for easy readout.
10. Low battery indication and auto power off.
11. The unit has a unique memory that retains all of its settings even when the power is off.
