Sulphite levels (measured as Na2SO3) need to be monitored in water applications such as boiler feed and effluent water, where the sulphite concentration must be maintained at about 20 mg/L to prevent oxidation or pitting of metal components. Sulphite ions are also toxic to aquatic life, so sulphite levels must be monitored in aquatic environments.

 

Hanna supply a variety of chemical test kits and automatic titrators suitable for measuring sulphite levels in water samples.
