Using DPD chlorine testing tablets. The most basic method is to use DPD chlorine testing tablets. In fact, the two methods above are essentially a DPD method. DPD stands for diethyl-p-phenylene diamine, the chemical compound which reacts with chlorine and changes the color of the sample water. The manner of using DPD testing tablets is similar to the liquid solutions mentioned above. Get a sample tap water, mix in the tablet, and compare the color results on the test chart. What makes it a little more complicated is that there are four DPD tablet variants which test different variations of chlorines. DPD1 is intended for residual or free chlorine, DPD2 for monochloramine, DPD3 for combined chlorine, and DPD4 for total chlorine.
