YSI Delivers Breakthrough Technology to Help Scientists Battle Nutrient Pollution

Posted: Thursday 1st April 2021

New EXO NitraLED Sensor Allows for Continuous Nitrate-N Monitoring at Scale.

Since 2010, the U.S. alone has spent over $1.1B to combat the effects of nutrient pollution in its waterways — including eutrophication, harmful algal blooms, and hypoxia.[1] The lack of simple-to-use, affordable technology for nutrient monitoring has left scientists with limited options to solve a growing water challenge.

To support the battle against nutrient pollution around the world, YSI, a Xylem brand, in late 2020 unveiled the latest addition to its industry-leading EXO Monitoring Platform — the EXO NitraLED UV Nitrate Sensor.

“For many years, the EXO [Monitoring] Platform has helped scientists understand complex aquatic dynamics,” said Zachary Henderson, EXO product manager. “The addition of this new sensor will help rapidly expand continuous nutrient monitoring networks around the world by leveraging existing EXO hardware.”

Data That Costs Less
Delivering continuous Nitrate (NO3-N) data at a fraction of the cost of existing technologies, the new EXO NitraLED Sensor allows scientists to build expansive monitoring networks for tracking nutrient pollution in real time.

Small, Lightweight, and Portable
Based on novel LED technology, EXO NitraLED is up to 70x smaller than other lamp-based UV Nitrate sensors, fitting within the palm of your hand — and it integrates directly into any EXO water quality monitoring system. No external hardware or infrastructure is required to collect continuous Nitrate-N data.

Understand the Impact of Nutrient Pollution
The EXO NitraLED makes it possible to gain a deeper understanding of the impacts of nutrient pollution. By adding the sensor to the thousands of EXO installations around the world, scientists can collect a full suite of water quality data with a single instrument.
