BAPI CO2 Duct and Harsh Environment Sensor




The BAPI CO2 Duct Sensor is an accurate and reliable way of incorporating demand controlled ventilation. It measure CO2 in ranges of 0 to 2000 PPM with a field of selectable output of 0 to 5 or 0 to 10 VDC.

The Duct unit samples duct air using an aspiration tube. The Harsh Environment unit features a ventilated BAPI-Box and is ideal for areas such as outdoor air plenums, equipment rooms, green houses and warehouses. For 0 to 2000 PPM units, the CO2 level is indicated as “Good, Fair or Poor” by three LED’s on the front of the unit. If it reached the top of the PPM range, the red LED will begin to flash.
