Description
Room combination Sensor for relative humidity and temperature – RFFT/RI/S
For measuring relative humidity and temperature in residential and office buildings. The transmitter records temperature and relative humidity via an internal Sensor and converts them into a standardized analog output signal 0-10V or 4-20mA.
