Information on the Amperometric Measurement of free Chlorine, Chlorine Dioxide and Ozone in Water

Overview:

For reasons of hygiene, drinking water, or any other water that people come into direct or indirect contact with, often has to be treated with compounds that destroy any micro-organisms contained in it. Chlorine, chlorine compounds or ozone are very often used as disinfectants. In this sensitive area, a high level of safety for the consumer is an absolute requirement, and for this reason, systems are used for fully automatic monitoring, control and recording of the disinfectant concentration.

Amperometric sensors provide the best means of monitoring the disinfectant concentration. This technical publication will present the electrochemical fundamentals and the application technology of such sensors in an easily understood form, for the interested reader.
