Smart Chamber

Available on backorder


  • Real-time flux processing with a LI-COR gas analyzer.
  • Connect to the embedded Wi-Fi web server to view configuration, real-time data, and diagnostics.
  • Portable and self-powered with long-lasting batteries.
  • GPS integration.
  • Use with a third-party gas analyzer or the Trace Gas Sampling Kit.

The Smart Chamber and all LI-COR chambers are specifically designed to minimize their impact on the natural soil activity with consideration toward:

  • Maintaining ambient pressure.
  • Achieving air mixing without a fan.
  • Accounting for the impact of altered diffusion gradient on the flux.
