eosFD soil CO2 flux

measure substrate CO2 flux via forced diffusion

overview

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
Weatherproof
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.
