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. 2. The system of claim 1, wherein the vat comprises a plurality of wheels. 3. The system of claim 1, wherein the sensor is disposed between a filtering media disposed within the vat and the pump. 4. The system of claim 1, wherein the sensor is disposed downstream of a discharge side of the pump. 5. The system of claim 1, further comprising a valve disposed between the vat and the pump. 6. The system of claim 5, wherein the valve is a three way valve. 7. The system of claim 6, wherein the sensor is disposed within a drain line connected to a first outlet of the three way valve, wherein the receiving space is fluidly connected to a second outlet of the three way valve, and the pump is connected to a third outlet of the three way valve. 8. The system of claim 6, wherein a drain line is connected to a first outlet of the three way valve, wherein the receiving space is fluidly connected to a second outlet of the three way valve, and the sensor is fluidly connected to a third outlet of the three way valve. 9. The system of claim 8, wherein the sensor is disposed between the third outlet of the three way valve and the pump. 10. The system of claim 8, wherein the pump is disposed between the sensor and the third outlet of the three way valve. 11. The system of claim 1, wherein the pump can operate to draw suction from the receiving space of the vat in a first mode of operation and in a second mode of operation the pump can operate to discharge toward the receiving space of the vat. 12. The system of claim 1, wherein the sensor is configured to measure an electrical property that is indicative of the total polar materials of the cooking oil. 13. The system of claim 1, wherein the sensor is configured to measure the electrical property of the cooking oil when the cooking oil flows past the sensor. 14. The system of claim 1, wherein the sensor is configured to measure the electrical property of the cooking oil when the cooking oil is still with respect to the sensor. 15. The system of claim 1, wherein said sensor is selected from a capacitance sensor, a voltage sensor, a resistance sensor, a dielectric sensor, a conductivity sensor, or a conductance sensor. 16. The system of claim 1, wherein said sensor is a coaxial sensor. 17. The system of claim 1, wherein the sensor is configured to measure two or more of capacitance, voltage, resistance, dielectric, conductivity, or conductance of oil that contacts the sensor. 18. The system of claim 1, wherein the sensor is configured to communicate with a display, with the sensor providing a signal that is proportional to a measured oil quality of oil proximate to the sensor. 19. The system of claim 1, wherein the controller is configured to send a signal to the sensor to modify a setting of the sensor to modify the calibration of the sensor. 20. The system of claim 1, wherein the controller is configured to adjust its settings for processing a signal received from the sensor that is indicative of the quality of the cooking oil within the loop of piping to modify the calibration of the sensor. 21. The system of claim 1, wherein the second sensor sends the signal to the controller wirelessly. 22. The system of claim 1, the vat comprises a filtering media.
