l Wide measuring range. It can measure the hardness of all metallic materials. Direct display of hardness scales HRB, HRC, HV, HB, HS, HL and three types of strength values immediately.
l Large screen LCD, showing all functions and parameters. With EL background light.
l Seven impact devices are available for special application. Automatically identify the type of impact devices, and with the user calibration function.
l Test at any angle, even upside down.
l Large memory could store 100 groups (Relative to average times 32～1 ) information including single measured value, mean value, impact direction, impact times, material and hardness scale etc.
l Battery information showing the rest capacity of the battery and the charge status.
l Original imported high speed thermal printer support the immediate printing function. It can save data permanently.
l NI-MH rechargeable battery as the power source. Charge circuit integrated inside the instrument. Continuous working period of no less than 150 hours (EL off and no printing).
l Auto power off to save energy.
l Excellent after-sale service system for high quality products--two years’ guarantee and all life maintenance. Easy to buy and comfortable to use.
