A system for transporting and measuring the quality of cooking oil exiting a fryer unit using a portable oil transport apparatus. The portable oil transport apparatus has at least one sensor for measuring the quality of oil passing through the system. The portable apparatus may be connected to a storage receptacle for disposing of spent cooking oil, or may be connected back to the fryer unit to reuse the oil, based upon the measured quality of the oil. The portable oil transport apparatus may have an oil filter for filtering out unwanted components contained in the cooking oil. The oil quality sensor is capable of measuring the electrical properties of the oil to determine whether the oil should be reused or disposed of.
