RHT-DM Duct Mounted Humidity and Temperature 2-wire 4 to 20mA or 0 to 10Vdc Transmitter

RHT-DM Duct Mounted Humidity and Temperature Transmitter
    Price Starting At: $287.00

    Overview

    The RHT-DM duct mounted temperature and humidity transmitters incorporate the best high accuracy and great stability relative humidity and temperature sensors. The RHT-DM convert the measured values into linear 4 to 20 mA signals or optionally 0 to 10 Vdc output. The microprocessor based circuit enables full configuration of output range when used with the optional TxConfig PC interface and the Windows® based software. The humidity signal can be configured to either relative humidity or dew point output.
