Overview
The Extech Current and Voltage Calibrator/Meter displays readings in mA or as a percentage of the 0 to 24mA range or as mV in voltage ranges. Five stored calibration values are easily retrieved for fast calibrations. Model 412355A features current plus voltage calibrations that are adjustable from 0 to 24mA and 0 to 20V as a calibration source. Model 4123000A features a current calibrator that provides 0 to 24mA output and provides 24VDC power to measure a two-wire current loop.
Applications
Applications include setup and calibration of process devices such as transducers, indicators, recorders, and controllers, troubleshooting and field service, and product design.

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.
