pH 6.4-8.4 Liquid Reagent (Phenol Red)

Overview

PH 6.4-8.4 reagent measure pH across the band that matters in treated water. Because pH governs how well chlorine disinfects, how aggressive a water is towards pipework and whether scale will form, it is normally read alongside the chlorine residual rather than on its own.

Key features

• Reads pH in the working band for potable water, pools and process water
• Ready-made reagent, so there is no weighing or dilution on the bench
• Supplied in the 65 ml size, item code PL65PhenRed

Frequently asked questions

How does pH affect chlorine dosing?
Chlorine disinfects far better at lower pH. As pH rises, more of the residual sits in the weaker hypochlorite form, so the same reading does noticeably less work.

Does this reagent work on its own?
Several photometric methods use two or three reagents in sequence. Check which components your method lists, and we will make sure the set is complete before it ships.

How should liquid reagents be stored?
Cool, dry and out of direct sunlight, with the cap firmly closed. Note the batch and expiry on the bottle, and work through the oldest stock first.
