The Automatic Turret Digital Display Micro Hardness Tester adopts computer software programming, high-magnification optical measurement system, photoelectric sensing technology, etc. Through software key input, it can adjust the intensity of the measurement light source, preset the test force holding time, switch between Vickers and Knoop test methods, file number and storage, etc. The large LCD display on the soft key panel can display the test method, test force, indentation measurement length, hardness value, test force holding time, number of measurements, and can input the year, month, and day. The test results can be output through a micro printer or connected to a computer via an RS232 interface. The automatic turret structure configured in the Automatic Turret Digital Display Micro Hardness Tester makes the measurement process more automated, with faster and more convenient measurement speed and efficiency. The menu structure of the Automatic Turret Digital Display Micro Hardness Tester allows selection of hardness scales HV or HK, mutual conversion of hardness values, and automatic storage of test results and data processing. The Automatic Turret Digital Display Micro Hardness Tester can also be equipped with a photographic device according to user's special requirements, which can photograph the measured indentations and material metallographic structure. It is suitable for determining the micro hardness of small, thin specimens, surface infiltration coating layers, etc., and for determining the micro hardness of brittle materials such as glass, ceramics, agate, gemstones, etc. It is an ideal hardness testing instrument for scientific research institutions, factories, and quality supervision departments for material research and testing. Scope of application: heat treatment, carburization, quenched hardened layers, surface coatings, steel, non-ferrous metals, and small and thin parts, etc.
