The CODEL SO2 & CO2 monitor has been designed & manufactured specifically for the marine industry. This robust sensor has major advantages over existing analysers which typically require extensive and elaborate maintenance. making them totally unsuitable for this arduous application.

  • Small compact design for minimal installation requirements
  • Integrated probe optical surface heating to protect against acid errosion
  • Integrated purge pump removes the requirement for external compressed air supplies
  • Combined CO2 / SO2 measurements for eas of %s calculations
  • Integrated data logging via RS485 Modbus
  • Real-time flue gas temperature measurements for high accuracy of contentration calculations
