FAS-DPD stands for Ferrous Ammonium Sulfate - N,N-diethyl-p-phenylenediamine, which is a titration method for measuring chlorine. This method provides more precise readings than traditional color-matching tests, making it valuable for pool and spa owners who want accurate results. In this product, "taylor r-0871" refers to the specific FAS-DPD titrating reagent used in Taylor test kits for testing free and total chlorine.
