Resumen
The CPEC306 with EasyFlux® is a turn-key, closed-path eddy-covariance (EC) flux system for long-term monitoring of atmospheric-biosphere exchanges of carbon dioxide, water vapor, heat, and momentum. A complete system consists of a closed-path gas analyzer (EC155 closed-path gas analyzer), sonic anemometer (CSAT3A sonic anemometer), data logger (CR6 datalogger), sample pump, and accommodations for a CDM-A116 allowing for additional sensors.
The gas analyzer’s intake design and small sample cell volume (5.9 mL) provide excellent frequency response (4.3 Hz cutoff frequency) with low total system power (12 W). Additionally, the vortex intake (United States Patent No. 9,217,692) greatly reduces maintenance and maintains frequency response compared to traditional inline filters.

Descripción detallada
The gas analyzer’s small sample cell volume (5.9 mL) minimizes the sample residence time (50 ms at the system’s nominal flow rate, 7 LPM). This gives excellent frequency response (5.8 Hz half-power bandwidth) with low total system power (12 W).
Eddy-Covariance Measurements
CO2 and H2O are measured with an EC155 Closed-Path Gas Analyzer. Three-dimensional wind speed and sonic air temperature are measured with a CSAT3A sonic anemometer head.
CPEC306 System Enclosure
The CPEC306 has two enclosures: a fiberglass enclosure that houses the CR6 datalogger, pump module, and optional CDM-A116, and the EC100 enclosure for data processing.
CPEC306 Pump Module
The pump module, a standard component of the CPEC306 system, consists of a small dual-head diaphragm pump with a brushless dc motor mounted inside a fiberglass enclosure. An integral cable connects the pump module to the CPEC306 system enclosure, which provides power, temperature measurement and control, pressure measurement, and pumping speed measurement and control.

-
Measuring the thermocouple with an accuracy of 0.01°C is difficult, if not impossible, because of polynomial errors, voltage errors, and potential temperature gradients across the data logger terminal strips.
-
No. The fine-wire thermocouples were designed to measure ambient air temperature.
-
Most Campbell Scientific dataloggers can measure a thermocouple without any external signal conditioning. Therefore, a dedicated module is not required.
-
The FW05 has a frequency response that is adequate for the eddy-covariance flux application.
-
Sensible heat flux is defined as the covariance of vertical wind and temperature fluctuations, measured with fast-response sensors. For more information, refer to a micrometeorology textbook.

Descargas
CR6 OS v.15.0.0 (9.05 MB) 27-08-2026
This download is for the CR6 datalogger. Execution of this download places the current CR6 Operating System file(.obj) and WiFi, RF45x and RF4xx operating systems (iobj) on your computer. It also updates the CRBasic Editor compiler and support files.
Why Update? New features and bug fixes. With this OS update it is recommended that you also update the Device Configuration Utility to the most recent version so that new datalogger features are available in the utility.
Note: Campbell Scientific always recommends updating operating systems on site if possible. When remote updates are required, it is recommended that you implement the necessary precautions to handle unexpected OS upload complications. All datalogger settings should be retained when updated remotely. If you choose to roll back to a previous operating system, the datalogger settings will be reset to default.
