CCO 5500 Carbon Monoxide (CO) Analyzer
The CCO 5500 Carbon Monoxide (CO) Analyzer uses infrared absorption spectroscopy to continuously measure CO concentration in combustion flue gases. The infrared source is mounted directly on the flue gas duct or stack on the side opposite from the receiver. Infrared energy is radiated by the source, through a chopper across the duct to the receiver. The receiver employs gas filter correlation and narrow band-pass optical filtration with two solid state detectors to determine the absorption of radiation by CO in the flue gas. ?????????????
