The replacement period for the standard sensor is 1 year. Replace it
when 1 year has passed after opening the bag. When using the
Temperature and Humidity Sensor, the surface can become dirty and
may decrease its sensitivity and accuracy. Therefore, if the unit is
being used in a dusty or smoky environment, it may be necessary to
change the sensor sooner than usual. The accuracy of the sensor
may decrease even within 1 year if it is used (kept) outside the
specified operation conditions.
●
When the sensor is not used, put it in the attached plastic bag with a
drying agent and keep it in a cool, dark place at 5 to 25
℃
and 30%RH
or less.
