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.

Building Reliable Systems: Hydroelectric Dam Monitoring in Western Pennsylvania
Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. 
 
In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. 
 
One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” 
 
Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.
Read MoreProtecting Chicago's Lakefront: Freshwater Beach Monitoring
Thousands of people flock to the Great Lakes every year to enjoy the freshwater beaches along the coast. As an urban hub with over 2.5 million residents, beachfronts in Chicago have regular visitors as well as tourists that recreate in the bordering Lake Michigan. 
 
According to the Chicago Park District, it is estimated that more than 100,000 residents and visitors per day use Chicago’s Lakefront trail during summer weekends. 
 
Proximity to the Lake is not only a recreational activity for Chicagoans, but also a part of the city’s history due to its role in domestic and international shipping routes. In addition, the Lake serves as a drinking water source and as an essential climate regulator in the region that acts as a natural air conditioning affect.
