The improved CEA 266 is a wall-mounted, infrared CO2
gas analyzer contained in a dust- and water-tight NEMA 4X enclosure. Ranges of 0 to 2,000 ppm, 0 to 5,000 ppm, 0% to 1%, 0% to 2%, 0% to 5%, 0% to 10%, and 0% to 20% are available. The sample gas is continuously drawn into the unit through a built-in air pump. A self-draining water trap and dust filter are included. The unit provides 0- to 5-vdc and 4- to 20-mA outputs, and two user-adjustable alarms and contact relays.
