MH310

MH310 Portable Hardness Tester  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. Large screen LCD, showing all functions and parameters. With EL background light. Seven impact devices are available for special application. Automatically identify the type of impact devices, and with the user calibration function.

MH310 Portable Hardness Tester 

Advantages

  • 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.
  • Large screen LCD, showing all functions and parameters. With EL background light.
  • Seven impact devices are available for special application. Automatically identify the type of impact devices, and with the user calibration function.
  • Test at any angle, even upside down.
  • 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.
  • Battery information showing the rest capacity of the battery and the charge status.
  • Original imported high speed thermal printer support the immediate printing function. It can save data permanently.
  • 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).
  • Auto power off to save energy.
