CPEC100

The CPEC100 is a closed-path eddy-covariance (EC) flux system for long-term monitoring of atmosphere-biosphere exchanges of carbon dioxide, momentum, water vapor, and heat. The turn-key system capitalizes on Campbell Scientific’s 15-plus years of developing, manufacturing, and operating atmospheric sampling systems for measuring trace gases. It uses miniature valves mounted on an innovative, custom-designed, compact manifold to perform automatic, on-site zero and span calibrations at the system operating pressure to ensure accurate gas concentration measurements.
