Overview
The Extech CFM/CMM Mini Thermo-Anemometer simultaneously displays ambient temperature, airflow, and air velocity on a large backlit LCD. Up to 8 easy-to-set area dimensions are stored in the meter's internal memory. Additionally, model AN200 includes a built-in non-contact IR thermometer that measures remote surface temperatures to 500°F with an 8:1 distance-to-spot ratio and laser pointer.
Applications
Use the Extech CFM/CMM Mini Thermo-Anemometer for HVAC installation, repair diagnostic and optimization, fume hood testing, installation and verification, ventilation system installation, servicing and analysis, environmental wind and temperature testing/analysis, automobile aerodynamic testing, and plant/facilities maintenance.

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.
