Water-ID - Phenol Red pH Reagent Tablets for PoolLab 1.0 – Pack of 500 - TbsPpH500

Water-ID – Phenol Red pH Reagent Tablets for PoolLab 1.0 – Pack of 500

These genuine Water-ID Phenol Red tablets are photometer-grade reagents designed to measure pH in pool and spa water across a range of 6.5–8.4. Each tablet dissolves in a water sample to produce a colour change that the PoolLab 1.0 photometer reads digitally, delivering fast, accurate and repeatable pH results. A pack of 500 tablets provides an ample supply for busy pool professionals and high-frequency testing schedules.

Why pH Measurement Matters

pH is one of the most critical parameters in pool water management. At values above 7.6, the effectiveness of disinfectants declines and skin irritation increases; below 7.0, chloramines form, mucous membranes are irritated, and metal components can corrode. Keeping pH in the correct range protects bathers, preserves pool equipment, and ensures that sanitisers work at full efficiency.

Kompatibilität

These tablets are calibrated exclusively for use with the Water-ID PoolLab 1.0 photometer. Using them with another device may yield inaccurate readings. Always ensure your PoolLab 1.0 is clean and correctly zeroed before testing. Drop one tablet into the filled cuvette, allow it to dissolve fully, then insert the cuvette into the photometer and read the result directly from the display.

Warum Echtheit zählt

Manufactured by Water-i.d. GmbH in Germany, these tablets are produced, blistered and packaged to photometer-grade standards, ensuring exact, consistent dosing with every test. The aluminium push-through blister packaging protects each tablet from humidity and heat, supporting the stated 2-year shelf life. Genuine Water-ID reagents are the only tablets validated for the PoolLab 1.0’s calibration curves.
