APPARATUS FOR MEASURING TOTAL ACID NUMBER OF OIL AND ESTIMATING LIFETIME OF OIL, AND METHOD FOR MEASURING TOTAL ACID NUMBER OF OIL AND OIL SENSOR USING THE SAME

摘要

Disclosed herein are an apparatus for measuring the total acid number of oil, an apparatus for measuring the lifetime of oil through the measurement of the total acid number of oil, a method for measuring the total acid number of oil, and a method of making measurements using an oil sensor. According to the disclosed invention, measurement accuracy can be increased through the use of a high-sensitivity conductance measuring sensor, the inventive apparatus can be applied to both lubricant oil and insulating oil, the size of the total acid number-measuring apparatus can be reduced.
