The eosFD is a revolutionary soil CO2 flux sensor that uses Eosense’s patented Forced Diffusion technology to measure soil CO2 flux directly. The eosFD is completely standalone—requiring only a minimal power source—delivering spatial freedom at any scale and opening up all sorts of possibilities for research.
- Zero spatial constraints
- Truly portable
- High temporal resolution
eosFD Soil CO2 Flux Sensor Highlights
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 data anywhere. (App note: Solar Power Sizing for eosFD)
Zero Spatial Constraints
The eosFD’s standalone design, with onboard CO2 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 methods for flux measurement collects a variety of data that is then combined to generate flux values. With the eosFD you eliminate that post-processing, as it reports high resolution flux directly.
Data Your Way
Download your 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.
