How are LI-COR chambers different?
The 8200-104 Opaque Long-Term Chamber and all LI-COR chambers have been carefully and intentionally designed to minimize their impact on the natural soil activity with consideration toward:
- Maintaining chamber pressure with ambient air.
- Achieving air mixing without a fan.
- Accounting for the impact of altered diffusion gradient on the flux.
- Minimizing the impact of the chamber on your soil environment.
