Intellical ISENH3181 is a digital, combination gas-sensing, ammonia ion selective electrode (ISE) with a with a replaceable membrane module, refillable outer body, a non-refillable gel 3M KCl reference with a double junction porous PTFE annular ring and built-in temperature sensor.
The electrode measures ammonia concentration in water samples. A 50mL bottle of 0,1 M NH4Cl Electrode Filling Solution is included with the probe.The laboratory version of this ISE is shockproof with its Epoxy plastic body.
The Intellical ISENH3181 probe is available with a 1 or 3 meter cable and is intended for laboratory use. The ISENH3181 is ideal for measuring ammonia concentrations in wastewater, drinking water and general water quality applications.

Long-Term Monitoring in the Chautauqua Lake Watershed
With a widely developed shoreline, Chautauqua Lake experiences influxes of non-point source pollution that have historically impacted the health of the lake. The Chautauqua Lake Association (CLA) has been monitoring the lake for over two decades, reporting on changes that have occurred over the years. A pair of local lake advocates, Jane and Doug Conroe, have lived on the lake for over 40 years and have played an important role in establishing monitoring programs and facilitating consistent data collection throughout the watershed. Doug has been involved with the Chautauqua Lake Association (CLA) since the pair moved to the area in 1980, and is currently serving as the Executive Director.

No Red Herrings: Data Driving the Largest Salt Marsh Restoration in the NE USA
The Herring River system encompasses around 1,000 acres in the Towns of Wellfleet and Truro, Massachusetts. In 1909, the Chequessett Neck Road dike was built at the river’s mouth, drastically limiting tidal flow. Today, it’s one of the most restricted estuaries in the northeastern United States. As a result, the area has suffered environmental decline, including poor water quality, hypoxia, lower pH, and salt marsh degradation. In 2023, the Town of Wellfleet received $14.7 million from NOAA’s Office of Habitat Conservation to fund the Herring River Restoration Project (HRRP). Francesco Peri, President and CEO at Charybdis Group LLC, uses a network of NexSens data loggers to monitor water level and water quality on the Herring River.

Carbon and Nutrient Monitoring in the Great Lakes Using Satellite Observations
Carbon and nutrients are the foundation of lake food webs and play an important role in the chemical and physical processes that shape aquatic ecosystems and various lake dynamics. Studying these cornerstones can help improve understanding of other lake conditions like harmful algal blooms, hypoxia, and phytoplankton community composition. The way in which these characteristics are monitored varies, though many rely on a proxy approach wherein parameters are extrapolated from the measurement of a different parameter. An assistant professor at Cleveland State University, Brice Grunert, is working to improve current strategies and take a satellite approach to monitoring the Great Lakes.
