Product details
HVS-50 Digital Vickers Hardness Tester
The HVS-50 digital Vickers hardness tester is a high-tech product that integrates optics, mechanics, and electronics. It has good reliability and operability, and is an upgraded product for small load Vickers hardness testers.
This machine adopts computer software programming, high magnification optical measurement system, photoelectric sensing and other technologies. Through soft key input, it can adjust the strength of the measurement light source, select the testing method and reference table, hold time, file number and storage, etc. It can display the test method, test force, measured indentation length, hardness value, test force hold time, measurement times, and can input year, month, date, test results and data processing. It can be printed out and connected to the computer through RS232 interface
The hardness tester is equipped with an optional photography device, which can take pictures of the measured indentation and material metallographic structure. It is suitable for measuring small, thin specimens, and parts after surface plating treatment. It is an ideal hardness testing instrument for research institutions, factories, and quality inspection departments to conduct research and testing.
