50 x DPD No.1 Test Tablets
Diethyl-p-phenylenediamene (DPD) tablet 1 dissolves rapidly to determine the chlorine or bromine content of your pool. It reacts with the pool water sample, changing its colour in various shades of red—the deeper the colour, the higher the concentration of the sanitiser (chlorine or bromine) present. All you need is your existing 5ml or 10ml pool water sample vial and the colour chart that came with the kit.
