PCS HFRR Lubricity Tester
The Falex HFRR Lubricity Tester evaluates the lubricating properties of diesel, biodiesel, and fuel additives under controlled temperature according to standard methods.
This high-frequency reciprocating rig measures wear scar diameter and friction coefficient, providing essential data for fuel formulation, additive development, and quality control. Typical applications include testing ultra-low sulphur diesel (ULSD) lubricity, screening new biofuel blends, comparing additive performance, and verifying compliance with fuel specifications.
