Online Type Biogas Analyzer

(Real-Time CH₄, CO₂, H₂S & O₂ Gas Composition Monitoring System)

Biogas plants must continuously monitor the quality of gas being produced to:

  • Optimize plant operation
  • Maintain consistent methane levels for compression or combustion
  • Protect engines, compressors, and gas upgradation systems
  • Ensure safety, efficiency, and compliance

TECTIKO’s Online Biogas Analyzer is an advanced, real-time gas monitoring device that measures key gas components like Methane (CH₄), Carbon Dioxide (CO₂), Hydrogen Sulfide (H₂S), and Oxygen (O₂) — giving you accurate gas quality insights 24×7.

Working Principle:

  • The analyzer draws a continuous sample of biogas through a probe line.
  • It uses NDIR (Non-Dispersive Infrared), Electrochemical, or Thermal Conductivity Sensors to detect and measure gas composition.
  • The system displays real-time concentration levels on a digital screen and sends data output to SCADA/PLC or a local panel.
