Abstract—This paper investigates the efficiency of lubricant analysis by using electrical conductor theory that applied to check the performance of the lubricant, it will be indicate a life cycle of lubricant. The measurement process has led Electrochemical cell, Induction coil and Hall Effect sensor for electrochemical field analysis and compare it with electrical conductivity. In conductivity measurement experiment, we consider dynamic measurement velocity at 80 RPM with a lubricant Semi-Synthetic 10W-40 type by 5 different life cycle samples ratio, Used lubricant : Unused lubricant are 100% (4: 0), 75% (3:1), 50% (2:2), 25% (1:3) and 0% (0:4). The voltage output of Hall Effect sensor of 100% sample measurement at 100 degree Celsius is higher than the voltage output of 75%, 50%, 25% and 0% sample are 7.04%, 12.21%, 21.25% and 28.65%, respectively. The average percentage of Hall Effect sensor errors with the dynamic measurement method of the 5 lubricant samples was 2.87. Even though this measurement method had a high percentage of errors, but it has a cost advantage over the current measuring devices such as the Viscometer which is expensive cost.
