Campbell Scientific’s EC155 is an in-situ closed-path analyser specifically designed for eddy covariance flux measurements. As a stand-alone analyser, it simultaneously measures absolute carbon dioxide and water vapour densities, sample cell temperature, and pressure. With the optional CSAT3A sonic anemometer head, the EC155 also measures three dimensional wind speed and sonic air temperature as part of the CPEC200 Closed Path Eddy Covariance System.

EC155 Benefits

• Slim aerodynamic shape for minimal wind distortion and body heating
• Low power consumption - suitable for solar-powered applications
• Optimal colocation of analyser and wind measurement
• Low noise
• Tolerant to window contamination
