Automated Soil Flux Chamber
The eosAC-LT/LO soil flux chamber’s large footprint, field-ready design and continuous measurement capabilities allows researchers to capture variability related to hot spots and hot moments for trace gases including CH4 and N2O. When coupled to one of the compatible analyzers, even the smallest changes in gas flux can be captured.
LARGE FOOTPRINT SOIL GAS FLUX CHAMBER
- Field-ready, durable design
- Large chamber footprint
- Transparent (-LT) or opaque (-LO)
- Stackable base
- Long-term, continuous measurements
- ABB-LGR, Gasmet & Picarro compatible
- Flux analysis software
The large and field-ready design of the eosAC-LT/LO allows you to cover more area at your field site. Plus, the extra volume and transparent or opaque design options mean you can now observe the effects of vegetation on trace gas fluxes.
The soil gas flux chamber uses the automated closed dynamic chamber technique (Pumpanen et al., 2004) for measurement of soil gas flux (e.g. CO2, CH4, N2O). Using the eosMX or eosMX-P multiplexer, up to 12 eosAC-LT/LO devices can be connected to a single gas analyzer for optimal spatial coverage. The chamber is based on a proven design that has been relied on by researchers for over 20 years (Drewitt et al., 2002).

- Agricultural N2O Emissions
- Wetland CH4 Emissions
FIELD REPLACEABLE COMPONENTS
Maximizing uptime is key to any field study, the eosAC-LT/LO is designed so that all critical components are field replaceable with minimal effort. This modular design saves time and money on repairs and minimizes data loss caused by instrument down time.
Setup of the new soil gas flux chamber is remarkably simple, so you are up and running quickly. Each chamber can reach up to 30 m / 100 ft from the analyzer, giving you a huge coverage area of about 2800 m2 / 30,000 ft2. When paired with the eosMX or eosMX-P multiplexer, users can connect up to 12 eosAC-LT/LO chambers to their Picarro, ABB-LGR or Gasmet analyzer for continuous measurement of multi-species gases including CO2, CH4 and N2O. The chamber’s two auxiliary ports allow you to connect additional sensors (e.g. PAR, soil temperature, soil moisture) to collect environmental data from your sites, and the eosAnalyze-AC software enables processing of logged data on any Windows-based computer.
DESIGNED FOR ACCURACY
