Extremes of Temperature and Humidity
As with any other reference or instrument under test that is inserted through the door, stem conduction
should be considered at the extremes of the HygroGen2’s measurement range.
A recommendation for conditions that are higher than 50°C, 90%rh, or 60°C, 80%rh is that the entire
RP2 measuring head is mounted on the inside of the door. At these extremes, condensation will form at
cold spots that can be introduced if there is thermal conduction with the ambient conditions.

An HG2-B8-9 bung which has a 9-17mm cable gland can be used to secure the head cable from the
outside of the door and provides further insulation.
