8200-104C Clear Long-Term Chamber
Specifically designed for researchers interested in long-term net carbon exchange (NCE) measurements, the 8200-104C Clear Long-Term Chamber uses patented and trusted technology with updates to weather resistance and sensor compatibility. This line of chambers now accepts industry standard SDI-12 connections for digital communication with sensors.
A clear chamber allows sunlight to reach your plants during a measurement. The chamber automatically rotates to and away from collars for automated measurements over long periods of time.
Design Your SystemHow are LI-COR chambers different?
The 8200-104C Clear Long-Term Chamber has been specially designed for NCE measurements. It includes technology and patents designed to minimize chamber impact on natural plant and 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.
- Allowing plant photosynthesis.
Net Carbon Exchange Measurements
With the 8200-104C Clear Long-Term Chamber, plants inside the chamber continue to receive light throughout a measurement. A clear-top chamber ensures that photosynthesis is not interrupted and enables you to measure NCE—a key variable for understanding ecosystem carbon balance. NCE is the gross primary production minus the ecosystem respiration.
