Water-ID – Phenol Red pH Liquid Reagent 65 ml (approx. 270 tests)

This 65 ml dropper bottle of Phenol Red liquid reagent is a genuine Water-ID consumable designed for accurate pH measurement in pool and spa water, covering the range 6.4–8.4. It is a photometer-grade refill specifically calibrated for use with the Water-ID PoolLab 2.0 photometer in liquid mode, delivering laboratory-quality results without the need to crush or dissolve a tablet.

pH is one of the most critical parameters in any pool. It directly influences how effective chlorine and other disinfectants are, and whether the water is comfortable and safe for bathers’ skin and eyes. Values that drift too high reduce sanitiser efficacy, while values that fall too low can corrode pool surfaces and equipment and cause eye irritation — making regular, precise monitoring essential.

Compatibilidad

This reagent is designed exclusively for the Water-ID PoolLab 2.0 photometer, used in liquid mode. Before testing, select liquid mode on the device menu — using this reagent in tablet mode will produce incorrect results. It is not intended for use with other photometer brands or with the original PoolLab 1.0 liquid-mode workflow without verification.

Cómo utilizarlo

Fill the cuvette with 10 ml of pool water, add the Phenol Red liquid reagent using the dropper, screw the lid on, and insert the cuvette into the PoolLab 2.0. Run the ZERO measurement first, then follow the on-screen prompts to obtain your pH reading. Each 65 ml bottle yields approximately 270 individual tests, making it an economical choice for pools tested frequently or managed by professionals.

Por qué lo genuino importa

Genuine Water-ID reagents are manufactured to photometer grade, ensuring the optical properties of the coloured solution precisely match the calibration built into the PoolLab 2.0 firmware. Using non-genuine or rapid-grade reagents can lead to systematic measurement errors. As a Water-ID product made by Water-i.d. GmbH in Germany, this reagent guarantees full compatibility and reliable, repeatable results every time.
