Abstract
A characterization factor monitor samples oil and provides a signal K corresponding to the characterization factor of the oil. Signal K may be used as a control signal or may be displayed by conventional display means to an operator. The monitor includes a refractometer and a flash point analyzer sampling the oil and providing signals RIt and F corresponding to the refractive index of the oil and to the flash point in degrees F of the oil, respectively. A temperature sensor senses the temperature of the oil and provides a signal T representative thereof. An output circuit connected to the refractometer, to the flash point analyzer and to the temperature sensor provides signal K in accordance with signals F, RIt and T.
