HV-30 small load Vickers hardness tester is the first generation of opto-electromechanical integration of high-tech products, the machine has a novel shape, with good reliability, operability and intuition, is the use of precision mechanical technology and optoelectronic technology of the new type of Vickers and Nuopu hardness testing equipment. The machine adopts computer software programming, optical measurement system. Through the soft key input, you can choose the measurement of Vickers and Knoop hardness, can adjust the intensity of the measurement of the light source, can choose to keep the load time, in the LCD display can show the test method, the test force, through the panel input measurement of the diagonal length of the indentation, the screen reads out the value of the hardness directly, easy to look up the table of the cumbersome, easy to use, high precision measurement. The Vickers hardness tester high-quality measurement of mounting and microscopic eyepieces a measurement reading structure, so that the hardness measurement is more correct and convenient. The Vickers hardness tester can be equipped with optional photography device, can be measured indentation and material metallographic organization for filming, and data processing and analysis, greatly improving work efficiency.

 

Performance characteristics.

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

2, the use of computer software programming, can be Vickers and Nu scale conversion 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 instit

tions, enterprises and quality inspection departments for research and testing of the ideal hardness testing equipment.
