1: •Room temperature is 23℃±5℃.

•It may cause degree of degradation when this unit is exposed to organic chemicals such as alcohol gas or sulfuric acid.

•It may cause degree of degradation for humidity when using this unit at high temperature/humidity environment for a long time.

• It may cause error of humidity value when this unit is exposed to high humidity environment (over 80%RH) for a long time.
