The climate meter is a combination of a thermometer for measuring air temperature and a hygrometer for measuring relative humidity. When used indoors, the meter displays the current indoor climate.
The correct temperature and optimum humidity ensure a comfortable and healthy living and working environment. Depending on how the room is used, room temperatures of 18 to 22° C are optimal. The most beneficial air humidity for humans is in the range of 35-65%.
An optimal room climate with the lowest possible consumption of heating energy can be achieved above all by careful, active ventilation. You can save heating costs by opening the windows briefly but wide several times a day. In cold weather in particular, the old, used and humid air is exchanged very quickly with the cold, but always dry fresh air.
