AQO Series

Outside Air CO2/RH/T

Available with analog outputs or protocol for BACnet RS-485
Integrated set-point relay
Optional field replaceable NDIR CO2 and RH elements
Now available with dual-channel CO2 element

DESCRIPTION
The AQO series exceeds project requirements for monitoring
outside air conditions for temperature, CO2 and relative humidity. APPLICATIONS
The AQO series is enclosed in an outdoor rated enclosure to protect
electronics from rain, overhead watering systems and harmful UV ▪ Controlling ventilation in response to occupancy
rays. The sensor can be ordered as stand alone temperature, CO2/ ▪ Facilitates compliance with ASHRAE 62.1 standard for
air quality
Temp, RH/Temp or all-in-one CO2/RH/Temp with a 0-5/10V analog ▪ Offices, conference rooms, and public assembly areas
or BACnet RS485 output. Now available with a dual-channel CO2 ▪ Hospitals (dual channel version)
element for more accurate sensing in continuously occupied spaces ▪ Greenhouses (dual channel version)
and greenhouses.
