Nitrate in Water

Nitrate (NO3-) forms in water when bacteria use dissolved oxygen to oxidize ammonium. Nitrate is mobile and may seep into streams, lakes and estuaries from ground water enriched by animal or human wastes or commercial fertilizers. High concentrations of nitrate can enhance the growth of algae and aquatic plants.

The traditional ISE nitrate sensor consists of a silver/silver chloride wire electrode in a custom filling solution. The internal solution is separated from the sample medium by a polymer membrane, which selectively interacts with nitrate ions.

Nitrate Monitoring

The EXO NitraLED UV Nitrate Sensor provides accurate, in situ measurement of Nitrate in freshwater environments. Utilizing state-of-the-art UV LED technology, EXO NitraLED™ is an optical nitrate sensor designed for long-term, low-drift monitoring. Built-in corrections for Natural Organic Matter (NOM) and Turbidity minimize interference in freshwater environments. Its compact form factor allows for seamless integration with any EXO Sonde.
