Palintest DPD 3 Tablets are used to accurately measure total chlorine levels in pool and spa water when used in conjunction with DPD 1 tablets. The DPD 1 tablet measures free chlorine, and the DPD 3 tablet is then added to determine combined and total chlorine, providing a complete picture of your pool’s sanitiser effectiveness.

Formulated for use with Palintest photometers and comparators, these reagent tablets produce clear, consistent colour results and are individually foil-wrapped to maintain freshness and reliability.
