Methane fermentation is a biotechnology capable of converting many types of waste biomass (including polymeric materials) to methane and carbon dioxide under anaerobic conditions. The aim of this work was to choose and verifies appropriate sensors for measuring methane and carbon dioxide concentrations in middle-sized laboratory fermenter during anaerobic bioprocesses. There were chosen two sensors based on infra-red spectrophotometry measurement procedure, which require specific arrangement of gas measurement loop. In this paper is described development in designing and testing of this loop under anaerobic conditions. Results and experiences of several carried experiments are included in this paper.
