Water-ID - PoolLab Phenol Red pH Tablets 250 Pack - TbsPpH250

Water-ID – PoolLab Phenol Red pH Tablets 250 Pack

These genuine Water-ID Phenol Red reagent tablets are the official consumable for measuring pH levels with the Water-ID PoolLab 1.0 photometer. Each tablet dissolves rapidly in a water sample, producing a characteristic colour change that the photometer reads precisely — delivering accurate, repeatable pH results every time. With 250 tablets per pack, this is the ideal choice for professional technicians or high-frequency pool testing.

Why pH matters in pool water

pH is one of the most critical parameters in pool and spa water management. An out-of-range pH directly affects the efficacy of disinfectants: high pH reduces chlorine’s sanitising power, while low pH can cause corrosion of metal components, irritation to eyes and mucous membranes, and problems with flocculation. Keeping pH within the recommended range of 7.0–7.6 protects bathers, equipment, and pool surfaces alike.

Compatibility

These tablets are formulated and calibrated exclusively for use with the Water-ID PoolLab 1.0 photometer. They are photometer-grade reagents — not intended for use with colorimetric test kits or test strips — ensuring the precision that professional water analysis demands. Always use genuine Water-ID tablets to maintain measurement accuracy and protect your photometer’s calibration.

How to use

Collect a water sample in a clean test vial, add one Phenol Red tablet, and gently agitate until it dissolves completely. Place the vial into the PoolLab 1.0 photometer and read the pH value on the display. The tablet format ensures exact, consistent dosing with every test. Store tablets in a cool, dry place, sealed against moisture, to maintain their stated shelf life and performance.
