The HI93711-D3 are high quality liquid reagents that allow for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the USEPA method 330.5 and Standard Method 4500-Cl G. The methods use a DPD reagent in which the reaction between chlorine and reagent causes a pink tint in the sample. By simply adding the 3 drops of HI93701A-T(F) and 3 drops of HI93701B-T(F) and 1 drop of HI93711-D3 total chlorine can be measured. By adding the reagents to the sample, the reaction will take place and one of Hanna’s compatible benchtop or portable photometers will determine the concentration from the color 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 0.00 to 5.00 mg/L total chlorine.
