1. A system for measuring the state of degradation of cooking oil comprising:
- a vat with a receiving space configured for receipt of cooking oil, the vat movable with respect to a housing of a cooking appliance used to cook food product with cooking oil;
a pump in fluid communication with the vat, the pump taking suction from the receiving space;
a sensor disposed in fluid communication within the vat and adapted to measure an electrical property that is indicative of the quality of the cooking oil within the vat,further comprising a second sensor, the second sensor being configured to interact with oil disposed within the cooking appliance, wherein the second sensor is adapted to measure the electrical property of the cooking oil that is indicative of the quality of the cooking oil, that is measured by the sensor, wherein the second sensor is configured to send a signal to a controller that is representative of the measurement of the electrical property of the cooking oil by the second sensor, and the controller is configured to compare the measurement of the second sensor with a measurement of the electrical property of the cooking oil received from the sensor, and the controller is configured to modify a calibration of the sensor based upon a determined difference between the measurement by the sensor and the measurement by the second sensor.
