RHT-P10 and RHT-XS

Temperature and Humidity Transmitter

The RHT-P10 and RHT-XS transmitter series incorporate the best high accuracy and great stability relative humidity and temperature sensors. They convert the measured values into linear 4 to 20 mA signals. The microprocessor based circuit enables full configuration of output range when used with the TxConfig PC interface and the Windows® based software.


RHT-P10 model is aimed at humidity and temperature monitoring in pressurized or vacuum systems. Sensor probe in Stainless Steel can be thread mounted in the supplied flange* or directly to the system wall or pipe.


RHT-XS is aimed at humidity and temperature monitoring in non-pressurized systems that require a remote sensor.


*The flange is not attached to the transmitter and must be purchased separately.
