TAYLOR R0870 DPD POWDER .25 LBS TAYR0870J

The Taylor R-0870-J DPD Powder (0.25 lb / 4 oz) is a bulk commercial-grade chemical reagent engineered for high-frequency pool and spa water sanitizer testing. Acting as the critical first indicator step in the premium FAS-DPD titration method, this fast-dissolving powder reacts instantly with active sanitizers, turning the water sample into a distinct pink color to confirm the exact presence of free chlorine. This generous 1/4 lb bulk container provides an exceptional per-test cost reduction compared to smaller 10-gram vials, making it the perfect solution for commercial facility operators, public pool management, and busy service routes.
