Overview
The Extech Hot Wire CFM Thermo-Anemometer/Datalogger date and time stamps and stores readings on an SD card for easy transfer to a PC. The datalogger measures air velocity and air flow with a telescoping probe designed to fit into HVAC ducts and other small openings. The probe extends up to 7.05 feet maximum length with cable. The meter stores up to 99 readings manually, and 20M readings via the 2G SD card, and adjustable sampling rates range from 1 to 3600 seconds. The type K/J thermocouple input allows for high-temperature measurements.

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.

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.

Continuous data collection in Lancaster County, Pennsylvania, started about 5 years ago, and the county will be making a major upgrade over the next year—switching from relying solely on the internal storage of water quality sondes to telemetry units that enable real-time data viewing.
