Acid Test for Oil

QwikCheck is an acid test that works for all cooling agents and oils. By placing QwikCheck against a service socket of the cooling media system that is to be checked, a small amount of cooling agent with oil is spurted onto a piece of paper. If the paper changes colour, there is acid in the oil, if it does not change colour, there is no acid in the oil. QwikCheck is a one-off test and only takes two seconds.
