Product Description:
HV-20 Vickers hardness tester is the first generation of high-tech optomechanical integration products, the novel shape of the machine, with good reliability, operability and intuitive, is the use of sophisticated mechanical and optoelectronic technology, a new type Vickers and Knoop hardness test equipment. The machine uses computer software programming, optical measurement system. Through the softkey input, you can choose the Vickers and Knoop hardness measurements, can adjust the intensity of light measurement, can choose the charge time, the LCD display can display test methods, test force, through the panel input measurement of indentation Angle length, the screen directly read the hardness value, easy cumbersome table lookup, easy to use, high precision measurement. The Vickers hardness of a unique measurement of measuring equipment and measuring micrometer eyepiece measurement reading structure, the hardness measurement more accurate and Convenience. The Vickers hardness tester can be equipped with photographic equipment that can measure the measured indentation and the microstructure of the material for photography, and data processing and analysis, greatly improving work efficiency.
Performance characteristics:
1. Automatic loading and unloading testing force, the test force can be selected at any time between 0 and 99 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 accurate
Measuring range:
small, thin, surface - coated test pieces and glass, ceramics, agate, artificial gemstones and other more brittle and hard materials. It is an ideal test instrument for research and testing of scientific research institutions, enterprises and quality inspection departments.
