Digital Micro Vickers Hardness Testing Instruments With Digital Eyepiece It has a more faster testing speed than other ordinary Micro hardness tester. The hardness value can be displayed directly and not need to enter the length of the diagonal. High quality imported components ensure the instrument can stable working for a very long time; 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 function and features:
1. Equipped with digital eyepiece and Data computing systems which accuracy can reach to 0.01um; Just click one button the hardness value will display on screen directly .
2. Main components adopted American 3M, Allegro, and Japanese Omron, NKK brand, ensure the instrument can stable working for a very long time.
3. High quality advanced optical system not only meet the definition of hardness testing requirements, but also can observe the micro structure of the material, image is very clear.
4. According to different visual habits of the operators, the strength of the light source can be adjusted. To avoid the visual fatigue for long time operation. Main purpose and Application:
5. With Vickers hardness and Knoop hardness testing capabilities, and testing force can be extended to 2KG. Automatic measuring the indentation diagonal length, the hardness and conversion hardness will show on the screen directly, no need to check hardness table.
6. Industrial digital screen can direct display hardness value, conversion hardness, testing method, testing force, dwell time, test number and testing process;
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).
1. Steel, nonferrous metals, tinsel, cemented carbide, sheet metal, metallographic structure.
2. Carburization, nitriding and decarburization layer, surface hardening layer, galvanized coating, coating.
3. Glass, chip and ceramic material. Specification:
