Chlorine dioxide (ClO2) is primarily used as a disinfectant, particularly in drinking water and also in a variety of industrial processes. It is highly effective and safe as it doesn’t produce trihalomethanes, the typical byproduct when chlorine is used. It is important to monitor the levels of chlorine dioxide in waters where it is used as a disinfectant to ensure there is enough present to remove harmful microbes and bacteria.


Hanna offer a wide range of portable and bench Photometers for accurate determination of chlorine dioxide levels.
