PoolLab Reagent Tablets – Phenol Red, pH (10 pcs)

Phenol Red reagent tablets are designed for the PoolLab digital photometer and enable accurate determination of the pH value of pool or hot tub water. The optimal pH range of 7.2–7.6 is a basic condition for effective chlorine disinfection, protection of swimmers‘ skin and a long service life of pool components. The device’s digital readout eliminates inaccuracies caused by subjective colour comparison in classic drop testing. Each tablet is precisely dosed for one measurement and the result is known within 10 seconds. The pack of 10 tablets covers weekly pH checks throughout the entire bathing season and is compatible with PoolLab 1.0 and 2.0 devices.
