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. 12 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. Thickness alarm setup. 9. LCD backlight display. 10. Low battery indication and auto power off. 11. Metric/imperial selection. Specifications: Measuring Range: 1.00~300mm(steel) Accuracy: ±(1%H+0.1)mm, H denotes the measured thickness.
