Water Testing - DPD 3 tablets

Description

The rapid dissolving tablets are used for testing Chlorine in drinking water using simple visual block, pool or disc Comparator (i.e. for use with non digital and non electrical comparators).

The DPD No.3 tablet is used for calculating Combined Chlorine (Mono- and Dichloramines) by adding the DPD No.3 to the water sample with dissolved DPD No.1. The result is Total Chlorine, from which the measured Free Available Chlorine (with the DPD No.1) is deducted to determine the Combined Chlorine result (mg/l).
