If you have a source of fresh NaOH you don't need the whole test - but you do need a set of directions for certain strength so if there is a conversion factor you know what it is. Once you have one test kit(any brand) just use the little cup, syringe for measuring the wine amount and directions. Follow the directions, but when you get to the part where you add phenylthalene and then NaOH until color change- just add the NaOH until the pH meter reads 8.2. Make any necessary calculations and you are done.
The Accuvin tests work good. The exception I find is the TA test. Since I have some high acid grapes being grown in the north, the test doesn't go high enough- only going to 1.0 and no higher. The pH test is much better than the strips, but certainly not as accurate as the meter, especially with reds. I find they influence the color readings.
