Online chlorine analysers are found in a wide range of applications from cooling towers to drinking water and wastewater.

Typically, a chlorine amperometric sensor is used as it can be mounted inline and give continuous readings. When an amperometric sensor is used, it is common to combine it with a pH sensor for pH correction of the chlorine result.

In some applications a colorimetric online chlorine analyser using DPD chemistry is preferable.
