HV-5 type low load Vickers hardness testerDetailed product description：

The HV-5 low load Vickers hardness tester is a high-tech product that integrates optics, mechanics, and electronics. It uses computer software programming and an optical measurement system. The machine is controlled by a microcomputer and can adjust the strength of the measuring light source through panel input. It can also display the test force value and holding time, making it easy to use and with high measurement accuracy.
This hardness tester is suitable for measuring small, thin specimens, and parts that have undergone surface plating treatment. It is an ideal hardness testing instrument for research institutions, factories, and quality inspection departments to conduct research and testing.

Its main functions are as follows:
1. Selection of low load Vickers hardness scale;
2 LCD screens synchronously display the change of test force;
The diagonal length of the indentation is entered through the panel, allowing the hardness reading to be directly read on the LCD screen;
4. Conversion comparison between hardness can be selected based on different materials;
5. Adopt adjustable cold light source measurement system, etc.
