photoThe CEA 266 is a wall mounted infrared CO2 gas analyzer contained in a water- and dust-tight NEMA 4X enclosure with digital display readout.
   Ranges of 0-2000 ppm, 0-5000 ppm, 0-1 percent, 0-2 percent, 0-5 percent, 0-10 percent, or 0-20 percent 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 is also provided. The unit includes 0-5 VDC and 4-20 mA outputs, and two operator adjustable alarms and contact relays.
   The instrument is applicable for use in indoor air monitoring, laboratory and research products, and various other applications where CO2 levels have to be monitored and/or controlled. CEA Instruments
