We offer the lowest total system power available for open-path (5 W) and closed-path (12 W) eddy covariance over the entire instrument operating temperature. This, combined with our ruggedized designs and low-maintenance operation, makes our systems the ideal choice for sites in remote or challenging conditions. We are unique among flux system providers in that we manufacture all key system components: 3D sonic anemometers, gas analyzers, sampling systems, and data loggers. This enables us to make our systems much more highly integrated, taking into account important system-level considerations such as sensor colocation and mounting, high-speed measurement synchronization, sensor aerodynamics, and whole-system frequency response. Finally, our patented colocated design of the IRGASON is the only open-path CO2/H2O gas analyzer that allows for flux calculations using instantaneous point-by-point conversion to CO2 mixing ratio, which eliminates the need to correct for density effects on the measurement.
