Rtec Hfrr Test Module on MFT-5000

HFRR Tester Overview

This next generation High Frequency Reciprocating rig HFRR testing machine has real time programmable force control , piezo sensors to measure real time friction, inline total wear scar depth, wide temperature range, and voice coil actuators. The reciprocating rig is mostly used to evaluate diesel fuel lubricity. The hfrr test can run on Rtec stand alone tester HFRR-2 or our Multi Function tribometer platform MFT-5000. The ease of use and advanced sensors makes this test highly reliable and repeatable. Typical test involves reciprocating ball over 1 mm disk with stroke at a frequency of 50 Hz for 75 min.

Module Features
● 0.1 to 300 Hz, 5 µm to 4.0 mm
● Real Time Force Control (or dead weights optional)
● Friction, Wear, Acoustic Emission, Film Formation
●  Piezo Load Sensors
● -60 to 250C Temperature Range

Detailed Information

HFRR test can be carried out on collected samples from field or for research purpose. The HFRR lubricity tester (both models) are fully automated and computer controlled. The setup is easy to calibrate and comes with standard oil and samples. It conforms to several ASTM standards including the most widely used ASTM d6079. The hfrr equipment is typically used predict the performance of additives, fuel injection application, study friction wear, diesel engine lubricity, lubricity improvers etc.
