Operating Conditions
The performance of the humidity sensor can be affected by long-term exposure to operating conditions at the extents of the logger’s
range. The sensor shows best performance when operated within the recommended normal temperature and humidity range of 5 to 55°C
and 20 to 80%RH, respectively. Long-term exposure to conditions outside the normal range, especially at high humidity, may temporarily
offset the RH signal (e.g. +3%RH after 60h kept at >80%RH). After returning into the normal temperature and humidity range the sensor
will slowly come back within the calibration state by itself. Prolonged exposure to extreme conditions may also accelerate ageing.
Typical tolerance of RH over Temperature:
