The Hanna Instruments-95761-01 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the EPA recommended method 330.5, in which the reaction between total chlorine and the DPD reagent causes a pink tint in the sample. By simply adding the Hanna Instruments-95761-0 reagents to the sample, the reaction will take place and Hanna’s compatible Hanna Instruments-96761 portable meter will determine the concentration from the colour that is produced. The results will be displayed in mg/L (ppm) of total chlorine. These reagents are designed to be used with samples that have an expected range of 0.000 to 0.500 mg/L free chlorine.
