Campbell Scientific’s EC150 is an open-path analyzer specifically designed for eddy-covariance flux measurements. As a stand-alone analyzer, it simultaneously measures absolute carbon-dioxide and water-vapor densities, air temperature, and barometric pressure. With the optional CSAT3A sonic anemometer head, the EC150 also measures three-dimensional wind speed and sonic air temperature.

Benefits and Features

  • Slim aerodynamic shape for minimal wind distortion and body heating
  • Optimal colocation of analyzer and wind measurement
  • Low power consumption—suitable for solar-powered applications
  • Low noise
  • Tolerant to window contamination
  • Measurements are temperature compensated without active heat control
  • Integrated analyzer and sonic anemometer mounting
  • Analyzer and sonic anemometer measurements are temporally synchronized by a common set of electronics
  • Field serviceable (easy access to chemical bottles)
  • Extensive set of diagnostic parameters to warn of questionable data
  • Fully compatible with Campbell Scientific dataloggers; field setup, configuration, and field zero and span can be accomplished directly from the datalogger
  • Maximum output rate of 50 Hz with 25 Hz bandwidth
  • Angled windows to shed water
  • Factory calibrated over wide range of CO2, H2O, pressure and temperature in all combinations encountered in practice
