Automatic Digital LCD Micro Hardness Tester

Video measurement automatic turret digital micro Vickers hardness tester is added a video measurement system on the basis of automatic turret digital micro Vickers hardness tester. The indentation can be clearly displayed on the 8 inch LCD screen in the course of the operation.Data can be observed by many people at the same time and can be measurement directly. Reduced manual operation errors and avoiding visual fatigue. So, the testing efficiency is greatly improved.

Main functions 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. Coating adopted car paint technology with white color. Looking more decent, and with the advantage of fullness, high gloss and more scratch resistance. Used for many years looking still bright as new.

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

4. 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 microstructure of the material.

5. With Vickers and Knoop hardness testing capabilities and the testing force can be extended to 2KG.

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

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 thebuilt-in printer.

9. Reserved image channelcan beconnected 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.
