Chloride ions (Cl-) are found in water and wastewater sources. Although not toxic to humans, it does have a negative effect on taste, so chloride levels must be monitored in drinking water. Chloride is corrosive in nature, so it is important to measure chloride levels in boilers and cooling towers. Chloride levels are also monitored in aquaculture and agricultural applications due to chloride being toxic to plant life.


Hanna offer a wide range of Photometers and ISE instrumentation that are ideal for measuring chloride levels.
