Manual chambers are a commonly used tool for measuring soil gas fluxes in the field. There are a variety of reasons why a researcher may choose a manual system over an automated one; however, the choice to use manual chambers doesn’t have to mean sacrificing all the benefits of an automated system. The eosMX recirculating multiplexer can be used in conjunction with manual chambers to easily and efficiently improve the robustness and reproducibility of flux measurements while simultaneously saving time on data processing.
To illustrate the use of the eosMX with manual chambers, we conducted an experiment in which three homemade static soil gas flux chambers were used to collect carbon dioxide (CO2) flux measurements from the garden outside the Eosense office in Dartmouth, Nova Scotia Canada.
