HygroFlex5-EX Humidity & Temperature Transmitter Instruction Manual
The Rotronic HygroFlex5-EX is a humidity and temperature transmitter designed for fixed installation in applications requiring high measurement accuracy. It features two analog current outputs for relative humidity, temperature, or derived parameters like dew point and enthalpy. The device supports interchangeable ATEX probes and includes an internal digital service interface for configuration and firmware updates via a PC.
