Key FeaturesSpecifications

Testing grease in conditions that mimic real-world mechanical stresses has always been a significant challenge for researchers. Starvation during these tests can skew results, making it hard to predict how a grease will perform under actual working conditions. That is why we created the PCS Instruments MPR GI – a brand new, optional accessory for the MPR.

This cutting-edge accessory delivers grease to the MPR’s three-disc contact in a controlled, accurate, and repeatable manner, guaranteeing that starvation doesn’t compromise test data. It’s a significant step forward in the testing of fatigue behaviour of greases, integrating smoothly with the existing MPR software for ease of use and complete user customisation.

  • Can accommodate greases with a consistency up to NLGI 3.
  • Can dispense up to 300 mL of grease before refill.
  • Test profiles can be automatically constructed to pause when a grease refill is required.
  • The MPR GI is provided as a kit that can be easily retrofitted to existing MPRs.
  • Intermittent or continuous grease supply is user-configurable.
