The CODEL ET 401 Cross Duct Carbon Monoxide (CO) Analyzers may be used as a complete standalone monitor or as part of an integrated emission monitoring, logging, and reporting system. The instrument is particularly suited to large/dirty processes.
The ET 401 is a single channel Cross Duct Carbon Monoxide (CO) Analyzers for the measurement of CO. It uses an infrared transmitter to project a beam of light across the duct to a receiver mounted opposite. The light beam is tuned to a specific wavelength where the CO molecules absorb the light energy but there is no interference from water vapor and other gases. Gas filter correlation (GFC) is used to isolate the interference of dust particulates and by using high-efficiency air purges the optical surfaces are protected from contamination.
