The principle of the Vickers hardness tester is that the surface of the workpiece is pressed by a stepping motor, and then the length of the diagonal of the indentation is measured by a reading microscope. Later, a conversion relationship between the diagonal and the test force is used to measure the Vickers hardness.

  In addition, Vickers hardness tester software can be installed to display the image through the computer display, which makes it easier and faster to operate and measure the hardness value.

  Japan's Takizawa High Temperature Micro Vickers Hardness Tester HMT-SHE system can be used to determine the Vickers hardness from normal temperature to high temperature. The temperature can reach 1200 ° C. It is suitable to verify the high temperature hardness of new materials such as heat-resistant metal materials and ceramic products. Measure Vickers hardness of different materials under certain temperature conditions.

  According to the national standard GBT 4340.2-2012, the error of Vickers hardness tester is different for different values of different forces.
