Duct Volatile Organic Compound Detector

No items found.


The duct volatile organic compound (VOC) detector manufactured by Ace Instruments allows for greater control over indoor air quality via VOC and temperature measurement in one solution. It is ideal for VOC and temperature monitoring in HVAC ducts in schools, offices, hotels, and public assembly areas.

The MOX-based (Switzerland) sensor VOC reliably measures both VOC and temperature to ensure occupant health, comfort and high indoor air quality levels. The transmitter is sensitive to most indoor environment VOC gases. Optional RS-485 Modbus communication provided for BMS/EMS connection.


  • Fast response MOX Sensor
  • Optional RS-485 communication 
  • ABS plastic duct enclosure with duct mounting bracket
