LaMotte 6197A-J DPD 3 Tablets – Total Chlorine Test Tablets (Box of 100)

LaMotte 6197A-J DPD 3 Tablets are used to measure total chlorine in pool and spa water, following the initial free chlorine test using DPD 1 tablets. When added to a sample that has already been treated with DPD 1, the DPD 3 tablet reacts with combined chlorine (chloramines) to display the total chlorine level as a pink color. This color is then read visually or with a compatible LaMotte photometer or color comparator.

Each tablet is individually foil-wrapped for long shelf life and reliable performance. This reagent is ideal for pool operators, service technicians, or facility staff conducting regular water testing.
