Dwyer Instruments CDTV-2D4F4 | Duct VOC & CO2 transmitter | Universal analog outputs | 2000PPM CO2 | 20K Ohm temperature sensor

Name: Dwyer Instruments CDTV-2D4F4 | Duct VOC & CO2 transmitter | Universal analog outputs | 2000PPM CO2 | 20K Ohm temperature sensor
Brand: Dwyer
SKU: CDTV-2D4F4
Availability: OutOfStock

Part Number : CDTV-2D4F4

A carbon dioxide/volatile organic compound (VOC) transmitter, the Series CDTV, Model CDTV-2D4F4 lowers energy costs in buildings by adjusting the amount of conditioned air according to the occupancy of the space. The transmitter can identify vapors that might need to be expelled during times of lesser occupancy by detecting both CO2 and VOC.
