Free and Total Chlorine High Range Reagents (300 tests)

The HI93734-03 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 USEPA method 330.5 and Standard Method 4500-Cl G. The reaction between chlorine and the reagents causes a pink tint in the sample. By first adding 5 mL of HI93734-0 reagent to the sample, followed by one packet of HI93701-0, the reaction with free chlorine will take place. For total chlorine, addition of 3 drops of HI93734C-0 is necessary as well. Following the appropriate reagent addition, Hanna's compatible HI96734 portable photometer will determine the concentration from the color that is produced. The results will be displayed in mg/L of free or total chlorine. These reagents are designed to be used with samples that have an expected range of 0.00 to 10.0 mg/L free and total chlorine.
