TEST STRIP DISPENSER AND INTERROGATION DEVICE FOR OPTICAL MONITORING OF OIL

摘要

Herein are disclosed are systems for optical monitoring of oil quality. The systems comprise a dispensing device and a cradle adapted to receive the dispensing device. The dispensing device contains a supply of test strips and comprises a mechanism for extending a test strip out of the dispensing device so that it can be contacted with an oil sample. The systems further comprise an interrogation module for optically interrogating at least one test zone of the test strip, so as to monitor at least one parameter of the oil sample. In one embodiment, the monitored parameter is the free fatty acid content of the oil, and the optical interrogation is performed by an optical reflectance method.
