‘One-Button’ Advanced Rockwell Hardness Tester

Buehler’s Wilson RH2150 is easy to program and offers an intuitive software interface with Buehler’s DiaMet hardness testing software. Use the external footswitch with the actuator-mounted clamping device to clamp and activate either manual or automatic start, as well as to release manually or automatically after test.

Wilson RH2150, is the latest Rockwell Hardness tester from Buehler (Lake Bluff, IL), updated and more advanced with easy programmability, advanced calculations and verification reminders to ensure compliance.

The RH2150 is available in two different sizes, with a vertical capacity of 10 and 14 inches (254mm and 356mm respectively). It is fully protected from outside influences with sheet metal casing and a load cell protection.

Buehler has improved the Rockwell with a clamping device attached to the actuator, extended scales, crash protection and a complete new user interface. Early user feedback highlights the ease of use, great software interface with intuitive icon-based controls, programmability and workflow automation, one-button testing and the available accessories, making the RH2150 flexible operation for many applications.

“The RH2150 was tested for weeks and months in harsh workshop environments and the consistency of test results and intuitive testing controls is clearly standing out and is the key requirement for this type of hardness testing machine,” says Matthias Pascher, hardness product manager. “We designed unique features, such as the clamping device, directly mounted on the actuator, intelligent footswitch controls, or the DiaMet software package for advanced testing and reporting solutions, including network connectability, which is more and more a need to ensure complete test result traceability.”

The machine performs hardness testing according to the current Rockwell standards, as well as plastics and carbon testing scales, and Brinell depth testing scales, all within the load range from 1 to 187.5 kgf.

With many testing scales available, the machine fits well in research labs or testing centers, where operators need access to various kinds of scales.

The intuitive user interface aligns with Buehler’s DiaMet hardness testing software, making it simple to learn and easy to use. A DiaMet package is available that will provide advanced features of DiaMet™ for the Wilson RH2150.

More User Benefits

  • Auto-stop clamping device holds down the sample and secures it during the testing.
  • The adjustable LED workspace illumination highlights the test location to ensure clarity and full visibility.
  • Indenter extensions are optionally available in several sizes to enable testing also on hard to reach test locations (only usable with clamping device).
  • The operator panel can be adjusted on the frame or taken off completely to put aside the machine if needed – ensuring full flexibility and an ergonomic test process.
  • USB connection for easy data output to memory drives.
  • In conjunction with the clamping device, the external footswitch can be used in multiple ways:

√ clamping and manual start
√ clamping and automatic start
√ manual release after test
√ automatic release after test

  • Rockwell Fast Mode allows the user to achieve test results in seconds.
