MRR(D)-150D1

Electric Rockwell & Surface Rockwell (Double Rockwell) Hardness Tester

 

Main Features

  • Direct reading of dial hardness value.
  • MRR (D) – 150D1 is an automatic loading and unloading – keeping- unloading system with simple operation and no artificial operation error.
  • MRR (D) – 150A1 is a manual loading and unloading of load, which does not require a power supply for operation.
  • It has stable performance, simple operation, and convenient usage.
  • Optimized mechanical structure, low electrical power consumption, linear small arc appearance.
  • Strong structure, good rigidity, accuracy, reliability, durability, high test efficiency.
  • An optional indenter extended hardness gauge is available.

 

Application Range

  • Rockwell: It is used to measure Rockwell hardness of ferrous, nonferrous metals and nonmetallic materials. It is suitable for measuring Rockwell hardness of heat treatment materials such as quenching and modulation.
  • Surface Rockwell: It is used to measure the surface Rockwell hardness of the ferrous metal, alloy steel, hard alloy and metal after surface treatment (carburizing, nitriding and electroplating).
