For most metals

Based on the hardness HL value, conversion can be performed

   to HRB, HRC, HV, HB, HS and Tensile strength

Impact devices D?DC?DL?C?D+15 and G are available for
   special applications

Test at any angle, even upside down

Lower and upper limits setting with low-high display judge

High accuracy +/- 0.5%

USB output for both recharging and data transfer to PC
