DWYER CDTV carbon dioxide & volatile organic compound transmitter

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.
