    CO2, Humidity and Temperature Transmitter

    CO2, Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to reduce installation time while lowering material cost.

    Overview

    CO2, Humidity and Temperature Transmitters reduce the number of sensors mounted on a wall or in a duct. By combining CO2, RH, and temperature in one device, system integrators are able to reduce installation time while lowering material cost at the same time. In order to achieve the best possible accuracy, the Series CDTR also includes digital barometric pressure adjustment and the ability to field calibrate the sensor. Universal outputs for both carbon dioxide and relative humidity allow users to select the transmitter output to be 4 to 20 mA, 0 to 5 VDC, or 0 to 10 VDC to work with virtually any building management controller.

    Features & Benefits:
    • Digital Intelligence Temperature Compensation Algorithm (DITCA™) eliminates error due to the self-heating effects of wall mount combination devices
    • Single beam dual wavelength NDIR CO2 sensor
    • Replaceable humidity/temperature sensors
    • Physical hardware lockout
    • Service display tool available for duct mount and wall mount units without an LCD
    • Relay output option
    Certifications:
    • CE
    • RoHS
