Carbon Monoxide Analyzer

The AAQMS-400 Carbon Monoxide (Co) analyser delivers precise and reliable performance at excellent value. It uses proven NDIR technology with standard range 0~50 ppm and 0.08 ppm detectable limit.


Infrared emmited by the light source is passed through the gas chamber containing the air sample,and the quantitative absorption of energy by CO in the sample cell is measured by the corresponding detector.

GFC(Glass Fiber Correlation)

GFC(Glass Fiber Correlation) technology is utilized to remove the interence caused by the mositure and other background.

Key Features
  • 14 meters optical path to perform high reliability.
  • Five years guarantee on GFC wheel.
  • Compliance with US EPA reference method.
  • Various Outputs Include Ethernet and Rs232.
  • User Friendly interface with Large Screen.
