Biogas Production | Measuring CO2 and Methane with Dual-Gas Sensors

Dual-gas sensors are ideal for monitoring methane (CH₄) and carbon dioxide (CO₂) levels in biogas production processes, including anaerobic digestion, landfill gas recovery, and composting facilities. They ensure efficient energy recovery, compliance with safety regulations, and environmental monitoring.

Methane is the primary energy carrier in biogas, while CO₂ dilutes its energy value. Monitoring these gases helps optimize energy production, reduce emissions, improve process efficiency, and ensure compliance with environmental and safety regulations.

NDIR technology measures gas concentrations by detecting the absorption of infrared light at specific wavelengths unique to each gas. It provides precise, real-time measurements for methane and carbon dioxide, making it ideal for biogas applications.

Our dual-gas sensors measure methane from 0 to 100% volume with a resolution of 0.01 % for 0-5% methane and 0.1% for 5-100% volume.

Multiple gas ranges enable the accurate detection of 0-100% vol. methane, 0-2% vol. propane and 0-100% vol. carbon dioxide with one sensor.

These sensors measure carbon dioxide from 0 to 5% volume with a resolution of 0.01 % and 0.1% for 5-100% volume. It also measures methane concentrations from 0 to 100% volume and carbon dioxide from 0 to 100% volume, offering flexibility for various biogas monitoring needs.
