Campbell Scientific’s IRGASON is an integrated open-path analyzer and sonic anemometer specifically designed for eddy-covariance flux measurements. It simultaneously measures absolute carbon-dioxide and water-vapor densities, air temperature, barometric pressure, three-dimensional wind speed, and sonic air temperature.
Benefits and Features
- Unique optical layout allows for a slim aerodynamic shape with minimal wind distortion and body heating
- Measurements are temperature compensated without active heat control
- Co-located analyzer and sonic anemometer measurement volumes
- Analyzer and sonic anemometer measurements are temporally synchronized by a common set of electronics
- Low power consumption; suitable for solar power applications
- Low noise
- Maximum output rate of 50 Hz with 25 Hz bandwidth
- Tolerant to window contamination
- Angled windows to shed water
- Field rugged
- Field serviceable (easy access to chemical bottles)
- Factory calibrated over wide range of CO2, H2O, pressure and temperature in all combinations encountered in practice
- Extensive set of diagnostic parameters to warn of questionable data
- Fully compatible with Campbell Scientific data loggers; field setup, configuration, and field zero and span can be accomplished directly from the data logger.
