Dual indenters micro vickers knoop hardness tester is a new hardness tester developed by company, the hardness tester have 2 indenters, can test vickers hardness and knoop hardness, with high-quality imported components, ensure the micro vickers knoop hardness tester working more stable. Protected by the state patent application of the lift & down system, after upgrading, the control system can provide more measuring data, and control more precise. |
Main functions and features :
1.Main components adopted American 3M, Allegro, and NKK brand, ensure the instrument can stable working for a very long time. 2.The independent research and development of lift & down system and positioning system, ensured the accuracy and repeatedly of the testing process. 3.The optical system designed by our senior optical engineer not only meet the definition of hardness testing requirements, but also can observe the micro structure of the material, image is very clear. 4.With Vickers hardness and Knoop hardness testing capabilities, and testing force can be extended to 2KG (HV2). By measuring the indentation diagonal length, the hardness will show on the screen directly, no need to check hardness table. 5. Industrial digital screen can direct display hardness value, conversion hardness, testing method, testing force, dwell time, testing times and testing process; The built-in printer can print test number, hardness value, average value, Max. Value, Min. Value, Xmax-Xmin directly, easy for operator to save the data. 6. One-time casting aluminum molding shell ensure structure more stable; Adopted car painting technology, pure white color looking more decent; High scratch resistance capability, used for years still brightness like new. 7. Reserved image channel, can be connected with computer, used the image analysis software to analyzing the physical and chemical properties of the material (for optional purchase). 8. Factory directly supply, we have products develop &design & produce ability, all the parts provide life-time replacement and maintenance service. 9. Equipped with data transfer software, can transfer the test data to computer for saving and editing from the hardness tester through RS232 port. |
Main application : 1. Artificial diamond, glass, crystal plate/chip, ceramic material
2.Steel, nonferrous metals, tinsel, hard alloy, sheet metal, metallographic structure. 3.Carburization, nitriding and decarburization layer, surface hardening layer, galvanized coating, coating. |
