HV-50 Vickers hardness testerDetailed product description：

The HV-50 Vickers hardness tester is a new type of Vickers hardness tester that uses precision mechanical technology and optoelectronic technology.
The machine is controlled by a microcomputer and can adjust the strength of the measuring light source through soft keys. It can also test the force holding time and display it in LEG. This machine adopts a unique measurement conversion and micrometer eyepiece one-time measurement reading mechanism, which is easy to use and has high measurement accuracy.

The three degree 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.
