Product Description:
HVS-5M/10M/20M/30M/50M Vickers hardness of the touch screen independent research and development of Shanghai Microcre upgrade products. It adopts the 5.6-inch true color touch screen, which is based on the design of audi's multi-media control principle, and is more intuitive and convenient for the fourth generation of high-tech products. The machine is novel in shape, with good reliability, maneuverability and intuitionistic, with the precision mechanical and photoelectric technology and the new dimension and knoop hardness tester.
Measuring range: small, thin shape, surface infiltration coating specimen and glass, ceramics, agate, brittle and hard material such as synthetic stones. Is to study the scientific research institutions, enterprises and the quality department and testing of the ideal hardness testing instrument
Performance Features:
1. Automatic loading and unloading testing force, the test force can be selected at any time between 0 and 60 seconds
2. Using computer software programming, can carry out the transformation between the vickers and knoop scale
3. Stable optical measurement system can adjust the strength of the light source
4. The panel screen displays the hardness value directly, which is convenient and high precision
5. Experimental results and data processing can be stored automatically by PC printer
