Product Feature:

• MRocky-50DDigital Rockwell Hardness Tester adopts a high‑precision EHMC digital Rockwell dial, which can display and set parameters including the current test scale, dwell time, and hardness conversion values.
• The instrument is equipped with a weight loading mechanism. During operation, simply apply manual preload until the buzzer sounds, then press the start key.
• The tester will automatically complete loading, dwell, and unloading, and display the hardness value. It features simple operation and clear indication.
• Integrated cast iron structure ensures 99% rigidity of the main body with minimized 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.
• High-precision EHMC digital Rockwell dial supports all Rockwell hardness test scales and scale conversion in compliance with ISO, GBT and ASTM standards.
• Supports upper and lower limit setting with out-of-tolerance indication.
• Real-time storage of hardness test results with automatic timestamp recording; data can be exported via USB or wireless connection.

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.
