Intellical ISEF121 is a digital, combination, Fluoride ion selective electrode (ISE) with a with a non-refillable gel reference with a single junction porous PTFE annular ring, and built-in temperature sensor. The electrode measures fluoride concentration in water samples. The laboratory version of this ISE is shockproff with its Epoxy plastic body.
The Intellical ISEF121 probe is available with a 1 or 3 meter cable and is intended for laboratory use. The ISEF181’s solid-state sensor design eliminates membrane replacement and allows for dry storage of the ISE.
The ISEF121 is ideal for measuring fluoride concentrations in wastewater, drinking water and general water quality applications.

Sargassum Surge: How Seaweed is Transforming our Oceans and Coastal Ecosystems
Until recently, Sargassum –a free-floating seaweed–was distributed throughout the Sargasso Sea , the north Caribbean Sea, and the Gulf of Mexico. But in the space of a decade, this seaweed has, as one scientist remarks , “Gone from a nonfactor to the source of a terrible crisis.” Driven by climate change, anomalous North Atlantic Oscillation in 2009-2010 and a glut of anthropogenic pollutants, sargassum has proliferated. Seasonally recurrent mats as deep as 7m now bloom in the “Great Atlantic Sargassum Belt” (GASB), which covers areas of the Atlantic from West Africa to the Caribbean Sea and Gulf of Mexico. Every year, millions of tons wash up along the shores of more than 30 countries . Dr.

Great Lakes Research Center: Designing Targeted Monitoring Solutions
According to the National Oceanic and Atmospheric Administration ( NOAA ), the Great Lakes have more miles of coastline than the contiguous Atlantic and Pacific coasts combined and contain 20 percent of the world's freshwater, making it a critical region to protect and conserve. Continuous monitoring and data-informed resource management are key components of managing waters in the region. Hayden Henderson, a research engineer with the Great Lakes Research Center (GLRC), designs and deploys monitoring platforms throughout the Great Lakes. With a background in environmental engineering, Henderson enjoyed the challenge of creating systems and making them work to obtain difficult, remote measurements.

Monitoring Meadowbrook Creek: Real-Time Data Collection in an Urban Creek
Meadowbrook Creek in Syracuse, New York, has been monitored by Syracuse University (SU) faculty and students for over a decade. Originally established by Dr. Laura Lautz in 2012, the early years of the program focused on collecting grab water samples for laboratory analysis and evaluating the impact of urban land use, human activities, and natural processes on water resources. Tao Wen , an Assistant Professor in SU’s Department of Earth and Environmental Sciences, took over the program in 2020 and upgraded the existing systems to include 4G modems that allowed for real-time data viewing. [caption id="attachment_39339" align="alignnone" width="940"] An overview of the Fellows Ave monitoring station along Meadowbrook Creek.
