The Extech Desktop Indoor Air Quality CO2 Monitor checks for carbond dioxide concentrations through the maintenance free NDIR CO2 sensor. Indoor air quality is displayed in ppm with good (0 to 800ppm), normal (800 to 1200ppm), and poor (>1200ppm) indications. A programmable visible and audible CO2 warning alarm will alert users if extreme readings are detected. Measurement ranges are 0 to 9,999ppm for CO2, 14 to 140°F for temperature, and 0.1 to 99.9% for relative humidity.


Applications include air quality monitoring in schools, office buildings, greenhouses, factories, hotels, hospitals, transportation lines, and anywhere that high levels of carbon dioxide are generated.

Flux towers track CO2 exchange between forests and atmosphere

Determining exchange rates of carbon dioxide between the earth’s forests and the atmosphere is turbulent business. Wind above forest canopies swirls as vortexes of air enter and exit stands of trees.  Across the globe, towers stand among the landscape, with sensors monitoring these eddies for carbon dioxide, water vapor and other gasses.  These so-called “flux towers†collect data on carbon dioxide exchange rates between the earth and atmosphere. Information gathered plays into the debate on the measurable effects of climate change. Carbon dioxide flows between the earth, atmosphere and ocean in an attempt to reach equilibrium. As automobiles and energy production facilities burn fossil fuels, more carbon dioxide joins to the mix.

To Protect and Preserve: Environmental Monitoring Central to Mission of Chesapeake Bay

In her 30th anniversary article about the Chesapeake Bay (Maryland) NERR, Jenn Raulin of the University of Maryland, Chesapeake Biological Laboratory, had this to say about the NERR: “CBNERR-MD is one of twenty-nine Research Reserves across the Country and along with just a handful of other Reserves is comprised of multiple sites." Former Deputy Secretary Frank Dawson who was acting manager of CBNERR-MD at the time of designation provides some insight, "The vision of the Reserve program in Maryland was to have multiple components that would reflect the diversity of the estuarine systems of the Chesapeake Bay, allow us to monitor change, research pressing issues, and provide opportunities for hands-on educational experiences.

Sensor Array Stretching Across the North Atlantic Reveals Drivers of Global Currents

Most of us are aware that the oceans of the world play a tremendously important role in both the regulation of the global climate and the uptake of atmospheric carbon. However, one might be forgiven for being less aware of the amazing complexity of the meridional overturning circulation (MOC) of the world's oceans. Scientists around the world are still learning about these drivers of our global climate system. The AMOC, that portion of the MOC in the Atlantic, is critical to average climate worldwide. Characterized by fluctuations from north to south and back again, warmer waters move northward on the globe, allowing deeper, colder waters to circulate toward more central areas.
