LaMotte 6905A-J DPD #3 Tablets – Total Chlorine Reagent (100-Count Blister Pack)

The LaMotte 6905A-J DPD #3 Tablets are used as the second step in the DPD chlorine testing process to measure total chlorine levels in pools, spas, and potable water systems. After the free chlorine is measured with DPD #1 (sold separately), the DPD #3 tablet is added to the same water sample to react with combined chlorine (chloramines), completing the reading for total chlorine.

Each tablet is blister-packed for easy dosing, long shelf life, and mess-free handling. The tablets are compatible with LaMotte’s ColorQ®, Octa-Slide®, and tablet-style water test kits.
