Overview
The TriOS NICO is a low-cost UV photometer for online measurement of nitrate in lakes/rivers, drinking water, and wastewater applications. The four detection channels enable a precise optical determination of nitrate by absorption, taking into account turbidity and organic substances that pose a problem for many products currently on the market. An internal temperature correction additionally increases stability of the measured values.
Easy Configuration
The TriOS NICO is compatible with the G2 interface box, allowing fast and easy configuration of the sensors using a web browser. The sensor can be easily integrated into existing process control systems and external data loggers using the native RS-485 Modbus RTU output, and the optional W55 V2 wiper reduces maintenance intervals by cleaning the optics before each measurement.

Data in Action: Heidelberg’s Nutrient Monitoring in Great Lakes Tributaries
In the early hours of the morning, when most people have yet to hit snooze for the first time, water sampling sites across Ohio are awake and actively collecting nutrient data. The samplers are active at noon, eight in the evening and four in the morning, but very few people would know or even think about the equipment. Included in those few is Jakob Boehler, field manager for the National Center for Water Quality Research (NCWQR) at Heidelberg University. For Boehler, these systems booting up every day represents valuable data points that will be used to educate the public, influence environmental policies and support future research. “There are 20 of these samplers going off across the state of Ohio and Southeast Michigan.

Three Decades of Research at Acton Lake
A multi-disciplinary team at Miami University, Ohio, has been studying the environmental change at Acton Lake for over three decades. Using three different NexSens buoys over this time, the team has an incredible archive of data that is helping build a picture of Acton’s past, present, and future. Until recently, a NexSens CB-50 buoy was used alongside other environmental monitoring at Acton Lake. In May 2025, the Miami team deployed a new XB-200 buoy , future-proofing their ongoing monitoring using real-time buoy systems. Acton Lake, a small hypereutrophic reservoir in southwest Ohio, covers 2.4km² and has a maximum depth of about 8m. The dam was built in 1956, and the lake has a large agricultural watershed.

Source Water Monitoring in Albany, New York: Tracing Water Quality throughout Tributaries
Thousands of US cities pull their drinking water from natural source waters like reservoirs, rivers, and streams, making overall watershed health a key consideration for water providers. In Albany, New York, the Albany Department of Water and Water Supply delivers drinking water to over 100,000 residents as well as monitors and manages the larger drinking water supply watershed. Hannah Doherty, Environmental Specialist at the Albany Department of Water and Water Supply , spends her days working with a small team to monitor the drinking supply and the connected water bodies. Doherty explains, “We’re the first to encounter the water that ends up being the drinking water.
