Introduction to Oil Acidity Tester

An oil acidity tester is a crucial device used to measure the acidity level of various oils, such as transformer oil, lubricating oil, and edible oil. The acidity of oil is an important parameter that reflects the degree of oil oxidation and degradation. Over time, oil can react with oxygen, water, and other impurities in the environment, leading to an increase in acidity. High acidity in oil can cause corrosion of equipment, reduce lubrication performance, and even affect the safety and stability of the entire system. Therefore, accurately measuring the acidity of oil is essential for ensuring the normal operation of equipment, predicting oil replacement time, and preventing potential failures.
