Designed to minimize changes to the soil and environment that can affect natural soil CO2 production and diffusion processes.
CO2 flux is calculated at the CO2 concentration of the surrounding ambient air. This minimizes effects resulting from the necessary increase in chamber CO2 concen-
tration during a measurement.
Measure in high CO2 environments up to 20000 ppm.
Patented pressure vent design allows pressure inside the chamber to track the ambient pressure under calm and windy conditions.
Chamber geometry facilitates mixing without using fans, eliminating potential for chamber pressure perturbation.
Wireless communications and LAN connectivity enabled.
Both survey and long-term chambers close automatically, eliminating variations caused by manual chamber placement.
Data analysis software is a powerful tool for viewing, recomputing, and quality control of data. 
New GPS accessory for survey measurements and Ground Level CO2 Concentration (GLCC) data mapping.
