MRocky 150 45A Automatic Twin Rockwell Hardness Tester scaled

Product Features & Applications

Product Features:

  • MRocky-150/45AAutomatic Rockwell hardness tester adopts a brand-new loading structure with high-speed head lifting, delivering extremely high testing efficiency to meet various specimen testing requirements, especially suitable for large workpieces.
  • Featuring a novel appearance, complete functions, convenient operation, intuitive display, and stable performance, it is a high-tech mechatronic product.
  • Supports all Rockwell and superficial Rockwell hardness scales.
  • Enables multi-value conversion of hardness scales.
  • Equipped with arc correction and compensation function.
  • High-speed head lifting, automatically adjusts descending speed upon sensing the specimen, and applies test force smoothly.
  • Touchscreen display and operation with dynamic curve graph for real-time monitoring of force sensor and displacement sensor status.
  • One-key operation for head descending, indenter loading, dwell, unloading, and hardness value display.
  • Marble platform for higher flatness.
  • Data storage function, automatically calculates maximum, minimum, average, standard deviation and repeatability; test results can be selectively deleted and output; built-in thermal printer, and Excel data files can be exported via USB.

Product Application:

  • Suitable for hardness measurement of quenched, tempered, annealed, hard castings, malleable castings, hard alloy steel, aluminum alloy, copper alloy, bearing steel, etc. Also applicable to surface quenched steel, surface heat-treated and chemically treated layers of materials, copper and aluminum alloys, thin plates, galvanized, chrome-plated, tin-plated materials, bearing steel, hard castings, etc.
