3 Product Description
3.1 Operation Principle
The humidity probe is continuously heated for avoiding the effects of condensation and high humidi-
ty onto the sensing elements, such as corrosion, high humidity drift or stray impedances. Thus, the
probe heating leads to outstanding long term stability. Based on the measured values humidity and
temperature, the EE211 calculates the dew point temperature Td whereas the separate, interchange-
able T-probe measures the ambient temperature. Ultimately, out of Td and T, the device calculates the
relative humidity RH as well as several other parameters like absolute humidity, mixing ratio, wet bulb
temperature or enthalpy.
