Product Description:
HVS-20 touchscreen Vickers hardness tester is an upgrade product developed by Microcre research and development. It adopts the 5.5-inch true color touch screen, which originated from the design of the audi multi-media control principle, and the operation is more intuitive and convenient to be the fourth generation of high and new technology products. The machine is novel and has good reliability, maneuverability and directness. It is a new type of dimension and Knoop hardness tester with precision mechanical and photoelectric technology.
Measuring range: small, thin, surface - coated test pieces and glass, ceramics, agate, artificial gemstones and other crispy and hard materials. It is an ideal test instrument for research and testing of scientific research institutions, enterprises and quality inspection departments
Performance characteristics:
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
