Auto Turret Digital Micro Vickers Hardness Tester (MHVD-10AP)
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.
Main functions and features:
1. Operational panel is concise and clear with menu structure, and with English and Chinese
interface, easy switching.
2. The hardness values, diagonal length, dwell time, testing frequency, environmental temperature, the maximum /minimum value of test, average value and repeatability can be displayed directly.
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 microstructure of the material.
4. The testing data able to be printed directly by the built-in printer.
5. 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. Ferrous metals, non-ferrous metals, castings and alloy materials.
2. Heat treatment and carbonation specimen, quenching and mini parts which with miscellaneous point.
3. Applicable to the Knoop hardness test of glass, ceramic, agate, precious stones and other non-metallic hard but brittle materials.
