Next Generation lubricity tester with real-time force and stroke control, piezo sensors and wide temperature range. Evaluate fuel lubricity, predict the performance of additives, study friction wear with our HFRR high frequency reciprocating rig and 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.


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.

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.
