The Dwyer 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.

Applications for the CDTV include:

• 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

Features

• Simultaneously outputs both CO2 and VOC measurements
• Single beam dual wavelength NDIR CO2 sensor
• VOC output is correlated to be equivalent to CO2 measurements
• Standard measuring ranges:
  • CO2: 0 to 2000 or 0 to 5000 ppm
  • VOC: 0 to 2000 ppm CO2 equivalent
• CO2 measurement accuracy: ±40 ppm ±3% of reading
• Enclosure rating:
  • Duct mount: NEMA 4X (IP66) for housing only
  • Wall mount: IP20
• Ideal for demand controlled ventilation and odor control in commercial buildings
