HFRR Tester FFT-M
The HFRR tester is a next generation lubricity tester with real-time force and stroke control, piezo sensors, and a wide temperature range. Evaluate fuel lubricity, predict the performance of additives, and study friction wear with our HFRR high frequency reciprocating rig and programmable force control (no dead weights). The HFRR tester measures real-time friction and has a flexure based design which makes it highly reliable and repeatable. It also provides a fully automated and computer controlled test, with easy setup.
Manufacturer
Rtec Instruments
Rtec Instruments develops and manufactures advanced mechanical and surface testing and measurement solutions for research and industrial applications. They specialise in combining techniques that provide a unique perspective in material testing. Their testers include tribometer, profilometer, scratch tester, high-temperature indenter, and corrosion testers. Furthermore, their testers provide the most robust and versatile platform in the market for testing friction, wear, adhesion, hardness, roughness, and film thickness from nano to macro-scale.

Key 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)

ASTM, ISO, DIN Compliant
Next-generation tester – compliant with current standards and future testing needs.
- A: Enclosure
- B: Down Force Control
- C: Position Control
- D: Environmental Controller
- E: Voice Coil

Software
The tester comes with a windows based computer that has an operation and data analysis software package.
The operation software is a recipe- based software that allows it to
run standard or previously created standard programs with a click of a button. The software provides change force, temperature, frequency, stroke, time, cycles, and humidity during each step. It also allows you to define endpoints based on several in-line data that are monitored. The software can be used for simple standard tests or advanced complex test methods.
The analysis package comes with visualization and statistical data analy- sis. Multiple files and reports can be opened for easy comparison. Data can be stored in binary or ASCII format.
