SERIES CDTA COMMUNICATING CARBON DIOXIDE DETECTOR

SERIES CDTA COMMUNICATING CARBON DIOXIDE DETECTOR

Series CDWP Carbon Dioxide Transmitter

Series CDWP Carbon Dioxide Transmitter

SERIES CDTV CARBON DIOXIDE/VOLATILE ORGANIC COMPOUND TRANSMITTERS

Simultaneously Outputs Both CO2 / VOC

The Series CDTV Carbon Dioxide/Volatile Organic Compound (VOC) Transmitter reduces energy cost in buildings by lowering the amount of conditioned air based on the occupancy of the space. By sensing both CO2 and VOC, the transmitter can detect fumes that may need to be exhausted during lower occupancy periods.

Product Applications

  • HVAC applications in hospitals, schools, and commercial buildings
  • Demand control ventilation
  • Odor control
  • Waiting rooms or other spaces that may be occupied 24 hours a day
