Auto Turret Micro Hardness Tester (HV-1000ZDT)

The new type Micro Hardness Testers (which were develop and improved by our institution) integrated with optics, mechanics and electricity. It is famous as its fashion and decent design, high testing precision, stable functions and simple operation.

Main Function and Features:

1. Special designed for improving the working efficiency of our customers as its automatically design. After adjusting the focal length, the objective lens and indenter can be switched automatically. And the testing force can load, dwell and unload automatically. Then the objective lens will automatically return to the initial focus state, and the length of indentation can be measured directly.

2. The independent research and development of lifting system and positioning system, ensured the accuracy and repeatedly of the testing process.

3. The optical system designed by senior optical engineer (who worked in the Shanghai Optics And Fine Mechanics Institute, Chinese Academy of Science) not only meet the definition of hardness testing requirements, but also can observe the metallographic structure of the material.

4. With Vickers hardness and Knoop hardness testing capabilities, and testing force can be extended to 2KG.

5. Testing method, testing power and duration time can be displayed directly on the LCD screen.

6. The hardness value can be displayed directly by entering the indentation diagonal length and avoid the complication of the look-up table.

7. 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.

8. The testing data able to be printed directly by the built-in printer.

9. Reserved image channel,can be connected with computer, used the image analysis software to analyzing the physical and chemical properties of the material.

Main purpose and the scope of the application:

1. Testing the hardness of metallographic structure, from the most soft material to the most hard material.

2. Carburizing, nitriding, hardened layer, surface coating, steel, nonferrous metals.

3. The hardness of the glass, ceramic materials.
