Large screen(128×64 dot matrix LCD), showing all functions and parameters. Test at any angle, even upside down. Support “forged steel (Steel)” material, when using the D/DC impact device test “forged” sample, can read HB value directly, without the need for manual checking table. Wide measuring range. It can measure the hardness of all metallic materials. Direct display of hardness scales HRB, HRC, HRA, HV, HB, HS, HL and three types of strength values immediately. Seven impact devices are available for special application. Automatically identify the type of impact devices. Large capacity memory could store 600 groups (Relative to average times32～1 ) information including single measured value, mean value, testing data, impact direction, impact times, material and hardness scale etc.
