Iodometry method
WebThis method can be used to measure very high chlorine concentrations from around 0.5 mg/L chlorine and above; however, it is not specific for free chlorine and will only give a measurement for the amount of total chlorine in the sample. Key Points. X Measures total chlorine only. High range total chlorine measurement from ~0.5 mg/L and above.
