The automatic turret type Vickers hardness tester is a high-tech product of optical and mechanical integration. The hardness tester is novel in shape, has good reliability, operability and repeatability, and is an ideal product for testing Vickers hardness. The machine adopts computer software programming and optical measurement system. Through the soft key input, you can select the measurement of Vickers and Knoop hardness, adjust the strength of the measuring light source, select the dwell time, and display the test method and test force on the LCD display. The indentation pair can be measured through the panel input. The length of the corner line and the screen directly read the hardness value, which simplifies the cumbersome look-up table. Easy to use, high measurement accuracy.
