LaMotte 6903A-J DPD 1 Tablets – Free Chlorine Test Tablets (Box of 100)

LaMotte 6903A-J DPD 1 Tablets are used for precise free chlorine testing in pool and spa water. These rapid-dissolving tablets react with chlorine in the sample water to create a distinct pink color when free chlorine is present. The intensity of the color corresponds to the concentration and can be read using visual comparators or digital photometers, including LaMotte’s colorimeters.

Each tablet is individually foil-wrapped to ensure long shelf life, resistance to moisture, and consistent performance. Ideal for pool service professionals, facility operators, and residential users who prefer tablet-based testing over liquid reagents.
