Rockwell-Hardness tester HP 150 R

The HP 150 R Rockwell hardness tester is specially designed for precise and standard-compliant Rockwell hardness tests. With a test range from 0.2 kg to 250 kg, it offers an exceptionally high Rockwell resolution of 0.0125 HRC.

Thanks to the motor-controlled force application, the HP 150 R enables reliable and reproducible hardness testing. The basic settings are flexibly configurable and can be adapted to individual test requirements.

The HP 150 R supports Rockwell hardness tests according to:

• DIN EN ISO 6508
• ASTM D 785
• ASTM E 18

The device can also be used to determine the ball indentation hardness in accordance with DIN ISO 2039 T1 for plastics.

Technical data

• Test room height: 320 mm - 800 mm (depending on version)
• Maximum specimen depth: 250 mm
• Dimensions: 1180 × 735 × 362 mm
• Weight: 215 - 245 kg (depending on version)
• Test load range: 0.5 kg - 150 kg

Precise force application & mechanics

• Force application in a closed control loop (closed loop method): 
  The closed loop principle ensures high-precision, force-controlled load application with a test force range of 0.2 kg - 250 kg without deviations. The test force is continuously measured and readjusted, guaranteeing maximum accuracy.
• Standard-compliant and flexible load application times:
  Thanks to the closed force control loop, the load application time can be individually adjusted to meet different standard requirements.
• Precision without overshooting:
  Unlike deadweight systems, continuous force control completely prevents overshoot - for maximum measurement accuracy and reproducibility.

Software and ease of use

• Individual tests up to fully automatic test sequence possible
• Hardness testing software HardWin XL
• Supports Windows 10 & Windows 11 (32/64 bit)
• Network-compatible for central data management
• Data export to Excel, Word, PDF or TXT
• Customer-specific test report creation
• 200 freely definable test programs for individual adaptation
• Password-protected calibration:
  Each Rockwell test method can be individually calibrated to correct for the influence of the indenter on the test result. Dedicated password protection ensures that only authorized users can perform calibrations.
• Wizard for easy operation & quick standard tasks
• Hardness value conversion according to DIN EN ISO 18265, DIN 50150 & ASTM-140-T1-9-2007 always included
• Option for replacement or control measurement of hardness values:
  • On the saved image
  • On the live image
  • With new impression
  • Quick access to archived test jobs

Accessories

Standard accessories for the HP 150 R:

• LCD color display for intuitive operation
• Folding beam as spindle protection for long-lasting use
• Clamping cap with movable hold-down device for flexible fixing of the sample
• Threaded spindle with handwheel for convenient height adjustment

Conclusion

The HP 150 R is a high-precision, flexible and standard-compliant Rockwell hardness tester that is suitable for a wide range of industrial applications. Thanks to motorized force application, closed loop technology and individual configuration options, it sets standards in Rockwell hardness testing.
