eosFD soil CO2 flux
measure substrate CO2 flux via forced diffusion
a new method to measure soil CO2 flux
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
- Low power requirements
FD technology has been tested and proven from pole to pole – surviving everything from meters of snowpack to frigid and sunless Antarctic winters.
