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.

San Francisco Bay’s Nutrient Phenomena
From the gold rushes to the birth of Silicon Valley, the San Francisco Bay Area is known for welcoming swaths of people looking for a new frontier of culture and natural beauty. It has had a front-row seat to some of America’s most rapid industrialization and population growth for the past 200 years and is now home to over seven million people. Tourism booms as people from all around the world come to see the iconic Golden Gate Bridge and the expansive bay that lies beneath. But the bay is not just for looks. It plays an essential role in supporting modern California living--and we are not just talking about surfing. 
 
 Water from every toilet flush, shower and load of laundry is treated and pumped back into the bay.

Microcystin, one of several toxins produced by the cyanobacteria that form harmful algal blooms (HABs), has become a popular topic of lake research as the human health impacts of HABs become better understood. Stone Lab is one of the leading groups in algal bloom research on Lake Erie and other lakes in Ohio. 
 
For more than 100 years, Stone Lab has conducted biology research and provided science education and outreach to the region. Over the years, thousands of individuals of varying ages have learned from the resources Stone Lab provides. 
 
Stone Lab’s Research Coordinator and Senior Researcher, Justin Chaffin, learned of Stone Lab while an undergraduate student at Bowling Green State University Fireland Campus.
Read MoreFrom Assessment to Angler: Continual Research Ensures Lake Erie Remains a Beacon of Freshwater Fishing
Lake Erie is well known for its abundant recreational fishing. Anglers come from across the country to try their luck at the “walleye capital of the world” and search for other freshwater species, such as bass, perch, and steelhead trout. 
 
 As one of the world’s largest freshwater fisheries, much effort is made behind the scenes to maintain fishing opportunities for visitors to enjoy year after year, efforts that often go unnoticed by the public. 
 
 One of the lake's most important economic and tourism centers is the city of Sandusky, home to the Sandusky Fisheries Research Station . As part of the Ohio Division of Wildlife, the unit serves as a base for assessing fish populations and managing harvest with partner agencies from around Lake Erie.
