Humidity/-temperature sensors in the I series are compact probe sensors with cable, connecting head or plug-in connection to measure relative humidity and temperature with high precision. They can be used for a wide range of applications.

The sensors in this series either have got a RS485-interface and are suitable for data transfer via MODBUS-RTU protocol
or they have got a RS232-interface and are suitable for data transfer via ASCII protocol.
