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.

Hydroelectric dams are a source of renewable energy, and many have taken the place of fossil fuel reliance across the United States. While they provide green energy to the grid, they also impact the environment above and below the dam. 
 
In order to protect these habitats and mitigate any potential harm, hydroelectric dam operators monitor water quality conditions above and below the dam to ensure conditions meet ecosystem needs. Eagle Creek Renewable Energy has several hydroelectric plants positioned throughout Pennsylvania, and each is managed and monitored by a team of professionals. 
 
One of these managers is Craig Goldinger, a regional manager with Eagle Creek Renewable Energy in Western Pennsylvania.

Environmental monitoring in the Caribbean may be essential, but it has also historically been placed on the back burner. Albert Jones, Instrumentation Officer for the Caribbean Community Climate Change Centre (CCCCC), explains, “Data collection itself is not what is considered one of those sexy activities where you can easily get funding.” 
 
Still, monitoring the water surrounding island nations is necessary to protect residents and the environment. The CCCCC works to establish environmental monitoring networks and systems in the Caribbean. One aspect of Jones’ work centers around data buoy instrumentation and deployment,—equipment that will be used to support Ecoforecasts for Coral Health Monitoring and to provide valuable environmental data to the public.
