HVS-5/10/30/50 Vickers hardness testerDetailed product description：

HVS-5/10/30/50 Vickers hardness tester:

The instrument adopts a precise structural design in mechanics, and the variation of test force values is controlled by sensors instead of the decrease or increase of weights, which makes the overall structure simpler, and the force values more stable and accurate. The testing process is controlled by the CPU in electrical aspects, and new technologies such as high-definition optical measurement system, photoelectric sensing, and cold light source are adopted in optics. The operation is input by the soft keys on the panel, which can preset the holding time of the test force, select the Vickers or Knoop test method, adjust the strength of the measuring light source, and other functions. And it can display the measured indentation length, hardness value, test force holding time, measurement frequency, etc. on the LCD screen. The hardness tester can also be equipped with CCD device, video device, and camera device according to users' special needs. Suitable for measuring micro Vickers and Knoop hardness of small and thin specimens, parts after surface infiltration treatment, and brittle materials such as agate, glass, ceramics, etc. It is an ideal hardness testing instrument for research and testing by scientific research institutions, colleges and universities, production enterprises, and testing institutions.
