High-Frequency Reciprocating Tester
The High-Frequency Reciprocating Tester is used in standardized and research-level lubricity testing, including:
Evaluation of diesel fuel lubricity and additive performance
Friction and wear analysis of petroleum products under boundary lubrication conditions
Lubricity measurement of lubricating oils, greases, and fuel additives
Comparative testing of different fuel formulations and additive packages
Research, development, and quality control testing in refineries, laboratories, and industrial facilities
Optional modules allow extended testing such as electrical contact resistance measurement, wear scar morphology observation, and gasoline lubricity testing.
