DPD N1 (Diethyl-p-phenylenediamine) is a reagent commonly used in the swimming pool and spa industry as a colorimetric indicator to test the free chlorine level in the water. It is a clear liquid that reacts with free chlorine to produce a pink color that can be measured using a colorimeter or a comparator. The intensity of the pink color is directly proportional to the amount of free chlorine in the water.
DPD N1 is typically used in combination with other reagents such as DPD N3 and DPD N2 to perform a full test for free and total chlorine levels in the water. DPD N3 is used to test for total chlorine levels, while DPD N2 is used to test for combined chlorine levels.
Overall, DPD N1 is an important reagent for maintaining the proper chlorine levels in swimming pools and spas, which is crucial for ensuring safe and healthy swimming conditions.
