Biogas is a renewable energy source created during anaerobic digestion. This occurs when the organic materials naturally break down in the absence of oxygen. The gas is formed from the digestion of waste materials such as manure, sewage sludge and other biomass substrates such as crop and food production waste. Controlling waste disposal, methane production and usage is vital to ensure the continuity benefits for the environment.

Built as a portable field gas analyser with laboratory functionality, the Rapidox 5100 Multigas Analyser is a high specification instrument designed for the analysis, control and monitoring of gas within biogas, syngas, anaerobic digestion and fermentation processes. Due to the range of high precision gas sensors, up to six gases can be measured concurrently including CO₂, CO, H₂O, O2, C₂H₄, SO₂, CH₄, H₂ and H₂S amongst others. When configured for applications where the gases contain energy (e.g. Biogas, Syngas) the calorific value of the gas sample is determined using thermodynamic calculations and simultaneously logged and displayed on-screen.

Equipped with a 180mm (7") full-colour touch screen interface with soft menu keys and an eight hour lithium-ion battery, all data is continuously logged. With a minimum of 12 months’ continuous data storage, the Excel compatible data can be downloaded via a USB memory stick.

Cambridge Sensotec also offers a range of Rapidox servicing options. To increase measurements and reliability, regular gas analyser calibrations are recommended.
