Overview
The CPEC300 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), and sample pump.
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.

Detailed Description
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
CO2and 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.
CPEC300 System Enclosure
The 24.9 x 34.0 cm (9.8 x13.4 in.) enclosure houses the EC100 electronics and the CR6 datalogger attached to the lid of the enclosure. The CPEC300 enclosure can be mounted to a tripod mast, CM106 tripod leg base, tower legs, or a large-diameter pole.
CPEC300 Pump Module
The pump module, a standard component of the CPEC300 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 CPEC300 system enclosure, which provides power, temperature measurement and control, pressure measurement, and pumping speed measurement and control.

CR6 OS v.11.01 (7.59 MB)05-24-2021
This download is for the CR6 datalogger. Execution of this download places the Operating System file(.obj) on your computer. It also updates the CRBasic Editor compiler and support files.
Why Update?Along with new features and bug fixes, this OS contains a changes related to WebSocket's, GOES, FileManage() and MQTT.With this OS update it is recommended that you also update theDevice Configuration Utilityto the most recent version so that new datalogger features are available in the utility.
Note:坎贝尔其ic 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.

-
No. A valve module is required to use the Scrub Module. Only the CPEC310 comes with a valve module.
-
The molecular sieve is a non-hazardous material that can be shipped to any country.
-
The molecular sieve is a direct replacement for the old magnesium perchlorate bottles. The molecular sieve may be used for any Campbell Scientific analyzer that used the old bottles.
-
The molecular sieve has been demonstrated here by our engineering department to be effective at removing CO2and H2O from the air sample. The change was made for two reasons:
- It was a safer alternative than using the previous chemicals.
- Increased shipping regulations for the chemicals limited the number of suppliers.
-
The bottles of sieve for drop-in replacement contain the pellets and a membrane on top. The membrane is necessary to keep the pellets contained while allowing gas to pass over the zeolite. The bottle has the same footprint as the old magnesium perchlorate bottles. The amount in each bottle is listed on the bottle. The amount of sieve needed for each analyzer is the following:
- The EC150 needs 22 g (drop-in bottle).
- The IRGASON®needs 22 g (drop-in bottle).
- The EC155 needs 22 g (drop-in bottle).
- The AP200 needs 500 g (refill).
- The 27423 needs 1000 g (refill).
- The 31022 needs 500 g (refill).
