Inhibited Mineral Oils Oxidation Characteristics Tester by ASTM D943

Summary

The Oxidation Characteristics Tester is applicable to Unused mineral insulating oil with inhibitor. It can also be used to understand the tendency of Unused mineral insulating oil to form acid and sediment before and after the induction period.
The use method is: the sample is kept at a certain temperature in the presence of copper catalyst coil, and at the same time, a constant oxygen flow is used to measure the time required for the volatile acid produced by the oxidation of the sample to increase to equivalent to the neutralization value of 0.28mgkoh/g, indicating the oxidation stability of the sample by the induction period.
