Pentair 1 oz #2 pH Test Solution
Product Overview
Phenol red indicator formulated for standard visual comparator blocks to read pool pH accurately between 6.8 and 8.2.
Formulated as a direct replacement reagent for Rainbow and standard 2-way or 4-way test kits, this Pentair RAINBOW™ SOLUTION 2 pH TEST in a 1 oz dropper bottle gives crisp color gradations without clouding the vial. Sized at 1 OZ., the controlled dropper tip dispenses uniform drops to prevent skewed pH readings caused by variable reagent volume.

Common Questions & Instructions
