LS252C is an integrated Hardness Tester with small size, which can measure the hardness of various metal materials. C-type impact device is adopted, with small impact force, suitable for testing the hardness of surface hardened layer and parts with small mass or thin thickness. The instrument adopts excellent dual-coil technology, which has good repeatability and measurement accuracy. The probe has a built-in direction sensor, which automatically compensates the measurement error of different impact directions. The system has a variety of built-in hardness scales, which can be converted between Leeb (HL), Vickers (HV), Brinell (HB), Shore (HS), and Rockwell (HRC), avoiding tedious manual calculations.
The instrument adopts C impact device, built-in a variety of metal materials to choose from, and has a wide range of applications.
