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.

Have You Heard? AI Buoys Revolutionizing Marine Mammal Monitoring in Whangārei Harbor, New Zealand

In one history, Whangārei Harbor, nestled in the lush hills of New Zealand’s North Island, gets its name from the Māori, “waiting for the breastbone of the whale.” It seems fitting, then, that it’s now home to state-of-the-art acoustic monitoring buoys listening for marine mammals around the clock. In September 2024, a team from Auckland-based underwater acoustics firm Cetaware Ltd installed NexSens buoys in Northport, a major commercial port at the entrance to the Whangārei Harbor. The first buoys to be installed by Cetaware in a permanent setting running 24/7, they use real-time artificial intelligence (AI) models to passively sense Delphinidae–from common dolphins to orcas.

Wildfires and Wildlife: Relocating Coastal Rainbow Trout to the Arroyo Seco Stream

Human interaction has negatively impacted the hundreds of streams that run through Southern California. Man-made river and stream diversions, channeling, and damming have changed the physical and chemical characteristics of these waterways. In addition to physical impairments, climate change is increasingly impacting the ecosystems of streams. To evaluate and mitigate these negative impacts, local groups are monitoring the riparian habitats of these streams and are conducting water surveys that document rainbow trout populations and evaluate water quality .
