Campbell Scientific’s EC155 is an in-situ closed-path analyser specifically designed for eddy covariance flux measurements. As a stand-alone analyzer, it simultaneously measures absolute carbon dioxide and water vapor 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.

EC155 Benefits

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