The eosFD is a revolutionary soil CO2 flux sensor that uses Eosense’s patented Forced Diffusion technology to measure soil gas flux directly. The eosFD is completely standalone chamber—requiring only a minimal power source—delivering spatial freedom at any scale and opening endless possibilities for research.

·  Zero spatial constraints

· Truly portable

· High temporal resolution

· Weatherproof

eosFD Soil CO2 Flux Sensor Highlights

Truly Portable

The eosFD’s minimal power requirement is met by modest battery, solar, or wind systems. And it weighs only 1.6 kg, so you can go get soil gas flux data anywhere. (App note: Solar Power Sizing for eosFD)

Zero Spatial Constraints

The eosFD’s standalone design, with onboard carbon dioxide concentration analysis and data logging in one tough package, means you can deploy an array that spans meters to kilometers of spatial coverage.

Direct Flux Measurement

Traditional chamber methods for flux measurement collect a variety of data that is then combined to generate soil gas flux measurements. With the eosFD you eliminate that post-processing, as it reports high resolution flux directly.

Data Your Way
Download your soil gas flux measurements from the eosFD’s internal storage using the included eosLink-FD software, or stream it via an analog connection to existing site dataloggers for easy integration with other data sources.
