OMEGA WTCL2-6980 水质测试套件 (DPD Chlorine/pH phenol red combination, 0.1 ~ 1.0 ppm, 1.0 ~ 6.0 ppm; pH: 6.8 ~ 8.2)

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)
