Chlorine Detection Powder is based on DPD chemistry. When combined with the salts and stabilizing reagents of the Chlorine Detection Powder, the DPD reacts with free chlorine in the water sample to turn a vibrant pink colour. The amount of free chlorine in your pool or spa (or even tap water) can then be estimated directly from the colour, or more accurately tested using our dropper based test kits.
