The Irgason integrated in-situ, open-path analyser and sonic anemometer can be used for eddy-covariance flux measurements. It simultaneously measures absolute carbon-dioxide and water-vapour densities, air temperature, barometric pressure, three-dimensional wind speed and sonic air temperature.
Benefits include: colocated measurement volumes for both analyser and anemometer; field serviceable (easy access to chemical bottles); slim aerodynamic shape for minimal wind distortion and body heating; fully compatible with Campbell Scientific data loggers; field set-up, configuration and field zero and span can be accomplished directly from the data logger; low power consumption - suitable for solar-powered applications; low noise.
