Advantage: 1.Machine with self-checking function,the turret will automatically checking turret position right or not and calibrated automatically when tun-on machine. 2. Adopted 4.3 inch touch screen, new advanced design for operation interface 3. With HV&HKscale & hardness conversionfunction 4. Digital eyepiece with encoder, D1, D2 data no need manual input to machine, easy operation 5. USB interface, test result can be save to u-flash directly.6. Menu structure interface, all data can display on screen 6. One-time cast aluminum shell, structure more stable. 7.Car painting technology, looking more decent and bright. 8. Reserved optical path for add CCD cameraand connect with PC (optional function) 9. OK/NG judgement function Application: 1.Widely used to test the hardness of all kinds of metal materials (steel, nonferrous metals, tinsel, cemented carbide, sheet metal, etc.) 2. surface layer / coating (Carburization, nitriding, decarburization layer, surface hardening layer, galvanized coating, etc.) 3.
