The automatic turret type microhardness 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 microhardness. The machine uses C language programming, high-magnification optical measurement system and optical dual-channel structure, new technologies such as optoelectronics and photocouple sensing. Through key operation, the length of the measured indentation can be input on the key, the hardness value, the conversion scale, the test force, the test force holding time and the number of measurements can be displayed on the LCD screen.
