Koehler K320S-200 Remaining Useful Life Evaluation Routine (RULER®)

Test Method
The portable Remaining Useful Life Evaluation Routine ( RULER® ) instrument measures the oxidative resistance levels of mineral and synthetic hydrocarbon oils, ester-based and biodegradable oils. Utilizing voltammetric techniques, the RULER® quantitatively analyzes the relative concentrations of antioxidants in new and used oils in order to monitor the depletion rates of the antioxidant protection package in the oil. The RULER® can be used proactively in order to determine proper oil change intervals and to extend oil change intervals through timely antioxidant additive replenishments. In addition, the RULER® can be used to quantify antioxidant levels of incoming and stored oil supplies and to detect abnormal operating conditions prior to equipment failure signalled by abrupt antioxidant depletion rates.
