Moist gas of up to approx. 80 % rh has only a slight impact on the measuring accuracy. However, make sure that no condensation can take place in the measuring device. The condensation could settle on the sensor which could lead to inaccurate measurements. In the event that a measuring device has come into contact with condensation, it can for the most part be rinsed with a dry gas, such as N2. See also the remarks in the operating instructions.
