The Extech Portable Indoor Air Quality CO2 Meter checks for carbon dioxide concentrations and calculates statistical 8 hour and 15 minute time weighted averages. The maintenance free NDIR sensor has measurement ranges from 0 to 5,000ppm for CO2, 14 to 140°F for temperature, and 0.0 to 99.9% for humidity.Programable audible alarms will alert users if readings detect a high concentration of CO2.
The built-in RS-232 interface captures readings to transfer to a PC. The data acquisition software and included cable record and document CO2, humidity, and temperature data. Applications include checking air quality in schools, office buildings, greenhouses, hospitals, and anywhere that high carbon 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.

Data-Driven Decisions: Tracking Sediment during the Klamath Dam Removal
The largest dam removal in U.S. history, the deconstruction of the Klamath Dam is slated to begin this summer. The project includes four dams along the Klamath River with the first and smallest dam, Copco #2, scheduled for removal first. As each of the dams are torn down, scientists and consultants will keep a close eye on the state of the Klamath River downstream to assess the impact of undamming the river. Shawn Hinz, managing partner and environmental toxicologist with Gravity Consulting , has been involved with the Klamath Dam project for over a decade. Hinz was a part of these earlier steps, representing the academic stakeholder position as a graduate student sitting on a board of other stakeholders.

From the Tap: Source Water Monitoring for Public Health
In regions with historically secure access to clean drinking water, few think about the work that goes into ensuring that the water they fill their cups with is safe. In reality, millions of dollars are invested in the infrastructure, equipment and teams involved in converting source water into drinking water. While all the work that goes into providing clean water often goes unnoticed, analysts like Michele Gilkerson, a water research analyst with the City of Columbus Division of Water, know exactly how much goes into securing safe water for millions of people. Gilkerson started with Battelle Memorial Institute in 1991 in their water ecology section. There, she saw how interesting source water monitoring could be, even though it isn’t often spotlighted in the environmental sector.
