» When the sensor is not to be used for a long period of time, please store it at normal temperature and

humidity.

» The included sensor is not water resistant. If the sensor gets wet, immediately remove the sensor from the

unit and wipe it with a clean cloth as soon as possible. Then allow the sensor to dry in normal room

temperature before using it again.

» Do not use the sensor on the human body.

Temperature-Humidity Sensor

» If extremely severe temperature changes occur, it may result in large errors in humidity measurement. Once

the sensor's temperature becomes stable, the measurements will return to normal.

» The temperature-humidity sensors will with normal use experience losses in precision and sensitivity over

time due to degradation. If the sensor is being used in an unsuitable environment (smoky or dusty places) it

may be necessary to change the sensor sooner.

» Do not expose to condensation, dampness, corrosive gases, or organic solvents.
