This Micro Essential Hydrion Auto Coolant pH Test paper tests the alkaline (pH) factor which indicates a breakdown in the auto coolant anti-freeze efficiency. It comes in a jumbo dispenser with one 50 foot roll and color chart. Fresh solutions have a pH of 9.0 or 10.0. As the coolant system ages, the pH factor goes lower. At pH 8.0, the solution is still good. At pH 7.0, the solution should be fortified with more antifreeze. At pH 6.0 or lower, the antifreeze should be replaced for alkaline protection of the radiator cooling system. Per each; 10/Carton. Micro Essential Labs #: AC-850.
