the Smart Chamber

The latest advancement in soil gas flux technology from LI-COR: quickly and comfortably assess the spatial variability of a broader range of gas species with expanded analyzer capabilities.

The Smart Chamber is a portable, self-powered 20 cm survey chamber featuring an embedded microprocessor and internal storage for real-time flux calculations when configured with LI-COR gas analyzers. The Smart Chamber can also be configured with non-LI-COR gas analyzers to measure fluxes of your particular gases of interest using SoilFluxPro™ software.

The Smart Chamber Difference

Like its predecessors, the Smart Chamber was designed to minimize and control for extraneous factors that induce measurement errors, providing the most precise and accurate measurements possible.

  • Bellows-controlled closure mechanism ensures that chamber placement has the same negligible effect on each measurement.
  • Patented chamber vent design maintains pressure equilibrium between the inside and outside of the chamber, even in windy conditions.
  • Flux calculations use an exponential function to compensate for altered diffusion gradients inherent in chamber-based gas flux measurements.

Built on this foundation, the Smart Chamber offers multiple technological innovations that will change the way you collect soil gas flux survey measurements.

LI-COR Trace Gas Analyzer Advantages

LI-COR trace gas analyzers provide high stability and precision, delivering unparalleled performance at an unmatched price point. Other benefits include:

  • Internal batteries, weather resistant (semi-waterproof) design, and optional backpack provide durability and portability for survey measurements in the field.
  • Wide temperature operating ranges (-25 °C to 45 °C) allow for operation in a variety of environmental conditions.
  • Wi-Fi-enabled* communications allow you to monitor your analyzer from your phone without taking a computer to the field.
  • Internal storage holds up to three months of data, and on-board display shows real-time concentration results.

*Wi-Fi only available in certain countries.
