Conventional antifreezes with inorganic inhibitor chemistry are formulated with "reserve alkylinity", and you can use pH test strips to test if the inhibitor package is excessively depleted. As the inhibitors are depleted, the solution becomes less alkyline.

The organic inhibitor package of Dexcool has a different range of pH, and pH is not a valid test of coolant condition.

Not sure about the hybrids, but their pH range is probably different than conventional inorganics, so I doubt if the pH testing is valid with them either.
