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.

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.Read More
Researchers in Quebec are taking underwater photos to get a fish-eye view of lake-shaping aquatic plants. They’re proving the use of a technique that could expand the study of plant populations that impact everything from a lake’s plankton and fish populations to its water levels.
Photo analysis could replace more expensive and labor-intensive methods.
“If you want to have good data, you have to dive and collect plants and dry them and weigh them,” said Andrea Bertolo, a professor of environmental science at the University of Quebec at Trois-Rivières . Soon, anyone with an underwater camera and a selfie stick could be contributing to this valuable science.Read More
In Saskatoon, Saskatchewan, pollution and runoff from storms and snowmelt are getting the close look they deserve, and there’s much more to examine.
Weather, from heavy spring storms to long months of snow and freezing temperatures, makes the polluting potential of runoff and snowmelt greater than and different from warmer climate cities, said Garry Codling in an email. In Saskatoon, potentially harmful elements in runoff can exceed the guidelines for runoff set by the Canadian government.Read More
