Special instructions

This digital comfort index thermo-hygrometer is an ideal
measurement device for checking your room ambient
conditions.
How does air humidity affect your health and your home
Excess humidity promotes the growth of undesirable organisms
in your indoor environment. Maintaining an inside humidity
range of 30 to 50% indoors helps prevent growth of molds,
mildew, and dust mites. Spending time in a moldy indoor
environment can wear down a person's immune system and
resistance to respiratory allergies and related infections. Indoor
air that is free from mold and mildew also smells fresh and
inviting.
Excessively dry indoor air can dry out skin and irritate your
throat and sinuses, making those areas more likely to become
infected. In arid climates or in the winter when the combustion
inside the furnace dries out indoor air, using a humidifier device
increases relative humidity--like the can did--but much more
precisely.
Indoor air that is too dry can cause wood to contract and crack,
especially thinner wood such as that used to build guitars and
violins. Over longer periods of time, excessively dry air can
even crack solid wood beams or logs plus some types of
plaster.
Active heating or ventilation can help achieve a comfortable and
healthy living environment.
About dew point temperature
Dew point is a measure of how much water vapor is actually in
the air.
The dew point is associated with relative humidity. A high
relative humidity indicates that the dew point temperature is
closer to the current air temperature.
For most people, the air feels humid when the dew point is
above 15.5℃(60°F)and uncomfortably hot and sticky when it
goes above 21℃(70°F)degrees.

Remark: Dew point temperature range is 0℃ to + 50℃.
When dew point temperature over 50℃ will display "HH.H",
below 0℃ display "LL.L".

Battery installation

1. Open the battery cover at the back of your mold alert thermo-
hygrometer.
2. lnsert 2×AAA batteries (alkaline batteries preferred)into the
battery compartment by observing the correct +/- polarity signs
inside the battery compartment.
3. Replace the battery cover. The unit is now ready to use.
