Operating temperature rang
Operating temperature rang is the rang of ambient temperatures in which the filter
can be
operated continuously. -10℃ ~ +60℃
Storage temperature rang
Storage temperature rang is the rang of ambient temperatures at which the filter can
be stored
without damage.
Conditions are as specified elsewhere in these specifications. -40℃ ~ +70℃
Reference temperature
