Product Features & Applications

Product Feature:

  • MRocky-150T Touch Screen Rockwell hardness tester is equipped with a high-definition color touch screen, which can display and set the current test scale, test force, indenter, dwell time, hardness conversion values, etc.
  • Adopting a weight-loading mechanism, the tester only requires manual preloading until a buzzer prompt is issued; then it automatically performs loading, dwell, and unloading, and directly displays the hardness value, featuring easy operation and clear indication.
  • Integrated cast iron structure ensures 99% rigidity of the main body, minimizing deformation. The housing undergoes natural aging treatment for over six months, delivering stable physical properties.
  • The lifting screw is heat-treated to a hardness of 35–40 HRC, ensuring structural stability and wear resistance.
  • Weights and levers are manufactured and calibrated with classic processes, offering high precision and mechanical fine-tuning capability.
  • 6-inch high-definition touch screen for display and operation, with dynamic image indication of the testing process and buzzer prompts.
  • Supports Rockwell hardness test scales; the corresponding indenter and test force are prompted after scale selection. Test forces are switched by rotating the load-changing handwheel.
  • Supports real-time hardness conversion between various scales.
  • Supports upper and lower limit setting with out-of-tolerance alarm, and features arc correction compensation.
  • Real-time storage of test results, automatic calculation of maximum, minimum, average, standard deviation, repeatability, etc. Supports multi-folder selection, with optional data deletion and print output.
  • Built-in thermal printer with fast printing speed; equipped with a USB port for direct data export to a USB flash drive.

Product Application:

  • Suitable for hardness measurement of quenched, tempered, annealed, and cold-hardened castings, malleable castings, hard alloy steels, aluminum alloys, copper alloys, bearing steels, and other materials.
