I've tried to get Taylor (1-800-837-8548) to explain why they market (at least) two PH test solutions e.g. R-0004 and R-0014. They only say that they are different (duhh!) and they are used in different test kits. I assume the colored films in those kits are coded for the apparent different "strengths" of 04 and 14.
But why are there two strengths of PH solution marketed. There is only one "strength" of OTO!. Right?
