Application

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.
