の開発が望まれている。However, in such a conventional lubricating oil testing machine, since the amount of the testing lubricating oil stored in the oil bath pan is large, the effective component in the lubricating oil during the testing is large. The change in concentration is slow, and it takes a long time to evaluate the performance of the test lubricating oil.
Further, when the test lubricating oil is an expensive material that is difficult to obtain, the performance of the test lubricating oil cannot be evaluated by the conventional lubricating oil testing machine that uses such a large amount of the tested lubricating oil. Because of this, the amount of lubricating oil to be inspected is small,
Moreover, it is desired to develop a lubricating oil tester that requires a short time for the evaluation test.
