Biogas potential tests are the most relevant tests today to predict biogas production from biomass. They are often done using expensive equipment such as pressure sensors or small-scale gas flow meter. In order to reduce costs and be able to have a higher number of replicates, it is necessary to provide research facilities with lower cost solutions without compromising precision of the measurements.

ReSource International has developed an open-source system based on classical water displacement measurement. The system called #Bioklik is based on the open-source Arduino board and operates automatically to measure a low flow of gas from fermentation processes. The #Bioklik system can also be used to monitor any other kind of fermentation process operated at laboratory scale with a continuous flow of gas such as brewing for example.
