and the moisture condenses – e.g. indoors on walls, outdoors it leads to the
formation of fog or precipitation.
Normal indoor air at 22°C and 40% humidity, which is generally found to be
comfortable, has – for example – a dew point of approx. 8°C. This information is
particularly helpful for preventing the formation of mould. As soon as the
temperature of e.g. external walls reaches the dew point or falls below it, moisture
will be deposited; in the long term this can lead to the formation of mould.
Remarks: The dew point temperature range of the hygrometer extends from 0°C
to 50°C. If the dew point temperature exceeds 50°C, “HH.H” appears on the
display; if it is below 0°C, “LL.L” appears on the display.
