Scope of application：
8MHVS-1000A Touch screen auto turret digital display micro Vickers hardness tester is mainly used for the determination of micro Vickers hardness of various metals and some non-metallic materials. It can measure the hardness of various parts (machined parts, forgings, cast iron, cast steel parts, etc.), non-ferrous metals, thermal post-treatment parts, various small and thin parts, glass, ceramics, agate, gems, etc, at the same time, it is suitable for the determination of the effective depth of carbonization and quenching hardening layer, coating layer, surface coating and heat-affected parts of welding parts. It can also be used to observe the internal metallographic structure of various metal parts and to collect, display and print the image.
Product introduction：
This product in the mechanical, optical, light source on the use of unique, precise design, so that the indentation imaging more clear, more accurate measurement. The new color 8-inch touch screen display (Figure 1) is adopted. The operation interface adopts menu structure. The hardness scale HV or HK can be selected on the operation panel. The tested hardness value is automatically calculated and displayed. Various hardness values can be converted to each other. This machine is equipped with 10 times digital measurement microscope and 40 times objective lens can participate in the measurement, so that the measurement range is larger, the application range is wider, and the large screen is adopted, the operation is more intuitive and clearer, and the test method, test force, indentation length, hardness value, test force retention time, measurement times, date, time, hardness conversion value and other functions can be displayed on the screen. It has the conversion scale, storage, printing and other functions, the indenter and objective automatic conversion positioning accuracy, higher efficiency, and has a threaded interface for connecting digital cameras and CCD cameras, easy to select computers and hardness analysis and measurement software.

The highlights of the new machine are as follows: The operation performance and function of the machine have advanced technology in the same industry.
1. The new machine not only has the function of data storage query and average value operation.
2. The new machine adopts a three-point card position for more accurate dot positioning, and the repeated dot positioning does not deviate.
3. The supporting shrapnel of the new machine adopts imported special customized materials, which have high toughness, high fatigue resistance and are not easy to deform (free replacement for 3 years can be provided, but working hours are charged).
4. The operation interface of the new machine adopts humanized format. The digital area and the function area are divided into columns. The surface keys are clearly marked in Chinese and English. At the same time, the menu has the function of switching between Chinese and English languages, which is suitable for convenient operation by personnel from many countries. The menu function classification is clear and detailed, and the light brightness, menu selection and objective lens selection all have memory functions.
5. The 10X and 40X objective lenses in the high-profile model have both measurement and observation functions (only 40X objective lenses in the same class have measurement functions).
6. Hardness conversion table classification refinement, is the current industry more perfect conversion table.
7. The light source system adopts long life, small heat, and free replacement for the 3 year.
8. car paint, paint quality high grade, anti scratch ability, use for many years is still bright as new
9. Hand-operated lifting body, high precision to ensure the stability of the indentation center point, the table rises and falls more smoothly
