EC150 Open Path Gas Analyser

Campbell Scientific's EC150 is an in-situ open path analyser specifically designed for eddy covariance flux measurements.

As a stand-alone analyser, 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.


EC150 Benefits

  • 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

 

Key Features

  • Serial output: SDM, RS-485, USB. Includes CO2 density, H2O density, ambient temperature, barometric pressure. When used with the CSAT3A head, also outputs Ux, Uy, Uz, sonic temperature. A range of sensor diagnostics are also output
  • Analogue output: 2 16-bit DACs for CO2 and H2O (0 to 5 Vdc)
  • Combination electronics for analyser, CSAT3A, barometric pressure and temperature  compensates for differences in measurement timing
  • CO2: Range - 0 to 1830 mg/m3; Noise - maximum 0.2 mg/m3
  • H2O: Range - 0 to 42 g/m3; Noise - 0.004 g/m3
  • Power: 5 W (steady state and power up) at 10 to 16 Vdc
  • Path Length: 15.37 cm
  • Output Rate: 5 to 50 Hz; user programmable
  • Output Bandwidth: 5, 10, 12.5, 20, or 25 Hz; user programmable
  • Analyser dimensions: 3.2kg; 29.7cm length; 3.2cm head housing diameter
