Analog Eyepiece Manual Turret Digital Metal Micro Hardness Testing Machine
After a test, the indenter will make a indentation on the surface of workpiece. Measuring the two diagonals’ length of indentation , then input the length value into machine, the hardness will show on the screen.
Vickers hardness numbers are reported as xxxHVyy, e.g. 650HV1
• 650 is the hardness number,
• HV gives the hardness scale (Vickers),
• 1 indicates the load used in kgf.
1. Main components adopted American 3M, Allegro, and Japanese Omron, 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. 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.
5. With Vickers hardness and Knoop hardness testing capabilities. By measuring the indentation diagonal length, the hardness will show on the screen directly, no need to check hardness table.
6. Industrial digital screen can direct display hardness value, conversion hardness value, testing method, testing force, dwell time, easy for operator to save the data.
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.
Main purpose and application:
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.
