The Extech Desktop Indoor Air Quality CO2 Monitor measures carbon dioxide, air temperature, and humidity. The instrument features a maintenance free non-dispersive infrared CO2 sensor. Indoor air quality is displayed in parts per million with good (380 to 420ppm), normal (<1000ppm), and poor (>1000ppm) indications. The visible and audible alarm with relay output has user-settable high and low alarms. The monitor also displays year, month, date, and time. It is calibrated through the automatic baseline calibration (minimum CO2level over 7.5 days) or manually calibration in fresh air. 


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

Notable Specifications:
  • CO2 Range: 0 to 9,999ppm

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.

First Environmental Monitoring System For Baltimore’s Inner Harbor

Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.

Parasite Behind Yellowstone River Fish Kill Found In Other Rivers

A parasite that caused a massive fish kill in Montana’s Yellowstone River has been found in at least seven other rivers in the state, according to the Bozeman Daily Chronicle . Scientists with the Montana Fish, Wildlife and Parks department made the find. So far, the parasite has been confirmed in the upper and lower Madison, East Gallatin, Bighorn, Stillwater, and Boulder Rivers. It had already been confirmed in the Jefferson and Shields Rivers. The microscopic parasite causes proliferative kidney disease, one of the most serious diseases to impact whitefish and trout. The effect of the disease on Yellowstone’s fish populations is exacerbated by other stressors like near-record low flows, consistent high temperatures and the disturbance caused by recreational activities.
