Series HT RH/Temperature Transmitter

Monitor and control relative humidity and temperature in building energy management systems with the Series HT Humidity/Temperature Transmitter. Designed for demanding HVAC/EMCS applications, the Series HT provides ±3% RH accuracy and ±1% stability per year. Routine calibration is not required with the fully interchangeable sensor. Two-wire connections allow easy instillation directly into air ducts or within a controlled area.  Dimensional Information
