Key Specifications/ Special Features:

Performance characteristics.

1.Automatic loading and unloading test force mechanism, the test force holding time can be arbitrarily selected from 0 to 99 seconds.

2.the use of computer software programming, Vickers and Nuclid scale can be converted between

3.stable optical measurement system, can adjust the intensity of the measurement light source

4.Panel display directly shows the hardness value, easy to use and high precision measurement

Measuring range: tiny, thin, surface penetration coating specimens and glass, ceramics, agate, artificial gemstones and other brittle and hard materials. Is a scientific research institutions, enterprises and quality inspection departments for research and testing of the ideal hardness testing equipment.
