Closed-Path Eddy-Covariance Systems Low-maintenance, robust, and integrated closed-path EC systems

About Closed-Path Eddy-Covariance Systems

Campbell Scientific offers closed-path eddy-covariance systems for fluxes of CO₂, H₂O (latent heat), sensible heat, CH₄, N₂O, and CO₂ isotopes. These systems are an optimum solution for long-term, low-maintenance flux monitoring thanks to the features of automatic zero/span, low-power requirements, and the revolutionary vortex intake (U.
