TriOS NICO plus UV Nitrate Sensor
Features
- Internal compensation for temperature, turbidity, and organic substances
- RS-485 Modbus RTU output for integration with data collection platforms
- Optional W55 V2 wiper cleans optics & reduces maintenance intervals
- Expedited repair and warranty service
- Lifetime technical support
- More
The new TriOS NICO plus not only offers the parameters NO3-N, NO3, NOx-N and NOx previously known from NICO, but has now been expanded to include numerous additional parameters. These include UVT254, UVT254n, SAK254, CSBeq, BSBeq, TOCeq, DOCeq, turbidity and TSSeq.
An internal temperature correction additionally increases the stability of the measured values. Equipped with the innovative G2 interface with web browser configuration and internal data logger, NICO plus has features that are significantly above the currently available devices on the market, in combination with an attractive price.
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.

Climate Change and Microplastics: Monitoring Lake Champlain
Most people go to Lake Champlain for its exceptional views and thrilling boating, but it’s also home to a wide variety of interesting aquatic research projects. From studying microplastics to thermal dynamics of the lake, Timothy Mihuc, director of the Lake Champlain Research Institute (LCRI) at the State University of New York at Plattsburgh (SUNY Plattsburgh), has spent his career studying aquatic ecosystems. 
 
 As an aquatic biologist, he’s the main investigator on Lake Champlain’s research studies while also managing their grants, employees, and their hands-on buoy work. 
 
 Over the years, LCRI has received a number of environmental grants that aid in its monitoring research.

On March 26th, according to The Baltimore Sun , a 984-foot, 112,000-ton Dali lost propulsion and collided with a support column of the Francis Scott Key Bridge, collapsing the structure. Soon after the event, search and rescue, salvage crews, and other emergency responders were mobilized after the collision. 
 
As salvage efforts progressed in early April, NOAA’s Center for Operational Oceanographic Products and Services (CO-OPS) responded to a request for real-time tidal currents data and deployed a current monitoring buoy—CURBY (Currents Real-time BuoY)—into the Patapsco River north of the Francis Scott Key Bridge.
Read MoreSoundscapes of the Solar Eclipse: Citizen Science Supporting National Research
On April 8, 2024, millions of people around the world had their eyes glued to the sky to witness a historic cosmic event. The total solar eclipse captured the headlines and the minds of many who became eager to gaze at the heavens as the sky went dark for a few minutes. However, not everyone used their sense of sight during the eclipse, some were listening to the sounds of the natural world around them as the light faded from above. 
 
 The Eclipse Soundscape Project is a NASA-funded citizen science project that focuses on studying how the annular solar eclipse on October 14, 2023, and the April 8, 2024 total solar eclipse impacted life on Earth. 
 
 The project revisits an initiative from the 1930s that showed animals and insects are affected by solar eclipses.
