1. Menu operation and color screen high-definition display. 2. It can quickly, non-destructively and accurately measure the thickness of the non-magnetic coating on the magnetic metal substrate and the thickness of the non-metal coating on the non-magnetic metal substrate. At the same time, it can automatically identify the magnetic metal substrate and the non-magnetic metal substrate. 3. Two measurement methods: single measurement and continuous measurement. 4. Three calibration modes: basic calibration, offset calibration, and zero calibration. Metric/English units and storage function. 5. Screen rotation, charging protection, multi-interface display, screen brightness selection. 6. Widely used in manufacturing, metal processing, chemical, commodity inspection and other testing fields. 7. Support USB and battery power supply. 8. Measuring range: 0-1500um/0-1.5mm/0-59mil 9. Lower limit diameter of magnetic metal substrate: 12mm 10. Lower limit thickness of magnetic metal substrate: 0.5mm 11. The lower limit radius of curvature of the magnetic convex substrate: 2mm 12. The lower limit radius of curvature of the magnetic concave substrate: 11mm 13. Lower limit diameter of non-magnetic metal substrate: 50mm 14.
