Factor & Method: DPD Chlorine/pH phenol red combination: Low concentrations of free, total, and various forms of combined chlorine are determined colorimetrically using DPD tablets or liquids, or by ferrous ammonium
sulfate/DPD titration. Higher concentrations are best determined using iodometric titration, which indicates total chlorine only
Test system: DPD tablet/ phenol red tablet 3 octet comparators
Range/Sensitivity: Low: 0.1 to 1.0 ppm; High: 1.0 to 6.0 ppm; pH: 6.8 to 8.2
# of Tests (# of reagent): 200 (5)
