The popular SRC-2 Soil Respiration Chamber is the industry standard for rapid, accurate survey measurement of soil CO2 efflux. The lightweight chamber is constructed of rugged PVC with a convenient handle for placement on the soil surface. A stainless steel ring provides a good seal on the soil surface or on collars.* A built-in temperature sensor measures air temperature near the soil surface a well as an internal fan to flush and mix the air.

The SRC-2 Soil Respiration Chamber is compatible with the CIRAS-4, CIRAS-3 and TARGAS-1 Portable Photosynthesis Systems, and the EGM-5 Portable CO2 Gas Analyzer

Optional collars (as shown in picture) are available.
