Product Description:
HV-5/10/20/30/50 small load Vickers hardness tester is the first generation of opto-mechatronics integration of high-tech products, the machine modelling is novel, has good reliability, operability and intuitive, is adopted the technique of precision machinery and new photoelectric technology vickers and knoop hardness test instrument. This machine uses computer software programming, optical measurement system. Through the soft key input, the choice of vickers and knoop hardness measurement, can adjust measure the strength of the light source, can choose insurance charge time, on the LCD screen can display test method, test force, through the input panel measuring indentation diagonal length, screen direct reading hardness value, simple look-up table of tedious, easy to use, high accuracy of measurement. The vickers hardness tester's unique outfit and micrometer eyepiece for a measurement reading structure, make the hardness measurement more accurate and convenient. The vickers hardness tester can be equipped with a photographic device, which can be used to shoot the indentation and material metallographic tissue, and the data processing and analysis can greatly improve the work efficiency.
Performance Features:
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 high precision
Measuring range: small, thin shape, surface infiltration coating specimen and glass, ceramics, agate, brittle and hard material such as synthetic gems. Is to study the scientific research institutions, enterprises and the quality department and testing of the ideal hardness testing instrument.
