The automatic turret Vickers hardness tester is a high-tech product integrating optics, mechanics and electronics. This hardness tester has a novel design and boasts excellent reliability, operability and repeatability, making it an ideal product for testing Vickers hardness. The machine adopts computer software programming and an optical measurement system. Through the input via soft keys, it allows for the selection of the measurement of Vickers and Knoop hardness, enables the adjustment of the intensity of the measurement light source, and makes it possible to choose the dwell time. On the LCD display screen, the test method and test force can be shown. By inputting the length of the indentation diagonal on the panel, the hardness value can be directly read out on the screen, which simplifies the complexity of looking up tables. It is convenient to use and has high measurement accuracy.
