The BAPI CO2 Duct Sensor is an accurate and reliable way of incorporating demand controlled ventilation. It measures CO2 in ranges of 0 to 2,000 ppm with a field selectable output of 0 to 5 or 0 to 10 VDC.
The Duct unit samples duct air using an aspiration tube.
The CO2 level is indicated as “Good, Fair or Poor” by three LEDs on the front of the unit.
If it reaches the top of the PPM range, the red LED will begin to flash.
