Transmitters RHT are designed to measure the temperature and relative humidity of gases and transfer the measured values via the standard 4 – 20 mA output.

The advanced technology guarantees outstanding sensitivity, stability and reliability. The distinctive feature of the RHT is high moisture resistance, small size and total independence from calibration during the whole life time of the transmitter. The RHT transmitters are delivered in the space and channel version.
They are used especially for:
  • check and control of technological processes (drying, ripening, etc)
  • check and control of air conditioning systems
  • humidity control in storage and other areas


The RHT transmitter is not suitable for operation in severely polluted atmospheres or petrochemical containing media.
