This is a Hana product instruction manual, which details the usage methods and accessories
The Hanna Instruments HI 38022 is a Total Chlorine High Range Test Kit designed for measuring chlorine concentrations in water supplies and polluted waters. The kit includes essential reagents such as Potassium Iodide Solution, Sulfamic Reagent, Starch Indicator, and Thiosulfate Reagent, along with calibrated plastic vessels and pipettes for accurate sample preparation and titration.

The concentration in mg/L (or ppm) is equal to the number of drops of Thiosulfate Reagent used to turn the solution colorless.
Use the 50 mL vessel instead of the 20 mL vessel and multiply the number of drops by 0.2 to get the concentration.
An iodometric titration method is used where iodine generated is equivalent to the chlorine in the sample and is calculated by titration with thiosulfate ions.
