CFLUX-1 Automated Soil CO2 Flux System • Fully automatic, programmable & stand-alone operation • Integral CO2 & H2O infrared gas analyzers • WiFi for setup & remote monitoring from desktop & mobile devices • Easy installation & setup • Optional sensors for soil moisture & soil temperature CFLUX-1 Automated Soil CO2 Flux System A dedicated, self-contained system for long-term deployment and unattended operation for measurement of soil CO2 flux. Ideal for both spatial and temporal analysis. With all key components built into a single station, there is no limit to where systems can be placed in the field. Shown: Stevens HydraProbe II is an optional plug and play sensor for measuring soil moisture and soil temperature. Sold separately. The CFLUX-1 Automated Soil CO2 Flux System is the latest innovation in a long line of trusted and tested technology for the measurement of soil respiration from PP Systems. Features that set the CFLUX-1 apart from other systems include: Built-in CO2 & H2O Gas Analyzers Soil Moisture & Soil Temperature Each CFLUX-1 Automated Soil CO2 Flux System has integral, The CFLUX-1 has one SDI-12 input and one analog input (0-1V) accurate, non-dispersive infrared gas analyzers for CO2 and H2O. for use with commercially available sensors for measurement Two independent infrared gas analyzers in each system means of soil moisture and soil temperature. Soil moisture and soil accurate measurement and fast response times regardless temperature can be measured and recorded along with flux data. of where each system is stationed – eliminating problems associated with long distances between chambers, analyzers WiFi and multiplexing devices. Onboard WiFi access point is used for setting up and monitoring A robust, water tight enclosure protects the built-in CO2 and the system remotely from your phone or computer. If connected H2O gas analyzers, electronics and terminal block connections. to a local computer with a router the CFLUX-1 system can be monitored from anywhere in the world with internet access. Auto-Zero Expanded Measurement Range Incorporated into each CFLUX-1 system, Auto-Zero eliminates for High CO the need for field recalibration and allows for fast warm-up, 2 Environments adaptation to changing ambient conditions and excellent The CFLUX-1 can be calibrated up to 30000 ppm for soil CO2 flux stability and accuracy for both CO2 and H2O. measurements in high CO2 environments such as volcanic areas. www.ppsystems.com sales@ppsystems.com CFLUX-1 Survey • Long Term • Stand-Alone Operation Onboard WiFi Access Point to setup & monitor remotely via mobile device or desktop Watertight Polycarbonate Enclosure Articulating Chamber for automated soil measurements with repeatable placement Solar Radiation Shield Vent Large Hemispherical Chamber (2500 cm3) ensures uniform air mixing & accurate Independent, Calibrated measurement Infrared Gas Analyzers (IRGAs) for CO2 & H2O Invertible All-Terrain Adjustable Legs Rugged Aluminum Frame 20.7 cm diameter (ID) Soil Collar Data Storage Software & Data Analysis The CFLUX-1 system includes full data storage direct to a Soil CO Efflux - Pelham, NH (USA) 2 5 40 USB Flash Drive (memory stick).
