SENVA AQ2D-BC2AAKD Total Sense Series Duct Air Quality Sensor
Duct Air Quality Sensor
Build a complete air quality system for indoor, duct, and outdoor Six environmental sensors: PMx, VOC, CO2, RH, T, barometric pressure BACnet/Modbus or analog outputs with set-point relay
DESCRIPTION
The Total Sense Series Duct AQ sensor provides more data for more advanced ventilation control while drastically reducing installation cost and time on a project. It includes a comprehensive selection of AQ sensing with carbon dioxide (CO2), relative humidity (RH), and temperature plus options for total volatile organic compounds (TVOC), barometric pressure and particulate matter (PM).
APPLICATIONS
- Measure duct air quality to validate filtration systems and deliver fresh air
- Verify effectiveness of IAQ strategies in post covid environment
- Energy management/building control

- Sense unhealthy particulates or TVOC’s in your duct system
- Industry-leading temperature and barometric pressure compensated CO2 sensing with non-dispersive infrared sensing element (NDIR), 15+ year life expectancy on CO2 sensing element; ±30ppm, ±3% of reading
- Tamper-proof
- Field-replaceable RH, Temp, and CO2 sensors ease maintenance
- 7-year limited warranty / 3 years on CO2 sensor – 2 years on all others
ORDERING
- CO sensor only availab le with display for calibration purposes.
- Choose Transmitter option for OLED temperature display and temperature readings over BACnet/Modbus.
The rmistor versions not available to display on OLED or to read over BACnet/Modbus.
