HFRR Tester Overview

Main Features:

  • Real-time down force control 
  • 1 to 200 Hz, 10 µm to 2.8 mm
  • Real time friction with piezo load sensors
  • Room to 180 °C (cooling and up to 400°C options available) 
  • Load Range up to 20N (More ranges available)

Evaluate fuel lubricity, predict the performance of additives,  and study friction wear with our HFRR high frequency reciprocating rig.

This next generation Rtec Instruments HFRR testing machine contains programmable force control (no dead weights). Combined with piezo sensors to measure real-time friction. The ease of use, flexure based design makes this tester highly reliable and repeatable.

Test collected samples from field or for research purpose. The HFRR provides a fully automated and computer controlled test. Setup is easy to calibrate and comes with standard oil and samples.

Each tester conforms to several ASTM standards including the most widely used ASTM D6079.  In addition to standard testing, the wide stroke, frequency, and load range allows development of new custom test methods. Perfect for understanding next generation fuel additives.
