CO12e Carbon Monoxide GFC Analyser

Preferred Communication Method
This field is for validation purposes and should be left unchanged.


The CO12e is a continuous carbon monoxide analyser. Its measurement principle is based on carbon monoxide detection by absorption of infrared light.

Service assistant inside: detects early signs of trouble, allows predictive maintenance, identifies the service needed and guides the service operations step by step: increased productivity on site, reduced downtime, more efficiency, less training

Specific Features:

  • Superior metrological performances for CO measurements in the range 0-300 ppm
  • Breakthrough mechanical design for weight and power saving as well as thermal insulation & reliability
  • Innovative conception of the optical module for excellent sensitivity and signal stability
  • Automatic or programmable response time adjustment, ensuring efficient monitoring of low concentration levels of CO
