New Closed-Path Gas Analyzer for Eddy-Covariance Flux Measurements

LOGAN, Utah – Campbell Scientific, with 35 years of world-class measurement experience, is pleased to announce a new closed-path analyzer, the EC155, for eddy-covariance flux measurements.

As a stand-alone analyzer, the EC155 simultaneously measures absolute carbon dioxide and water vapor densities, air temperature, and barometric pressure. With the optional CSAT3A sonic anemometer head, it also measures three-dimensional wind speed and sonic air temperature.

The EC155 features a slim, aerodynamic shape for minimal wind distortion and body heating, along with optimal co-location of analyzer and wind measurement.  It also has the benefits of low noise output and low power consumption (meaning this analyzer is suitable for solar-powered applications), and it is tolerant of window contamination.

A complete closed-path system requires the integration of pump, valves, datalogger, sonic anemometer, and the EC155. All of these components have been packaged into the CPEC200, a field-ready system with all the engineering done for you. The closed-path analyzer is compatible with many Campbell Scientific dataloggers, including the CR800/850, CR1000, CR3000, and CR5000. 

Campbell Scientific, Inc., is a worldwide manufacturer of dataloggers, data acquisition systems, and measurement and control products.
