TFA

This functional thermo-hygrometer is an ideal measuring instrument for monitoring the indoor climate. You can easily keep an eye on the temperature and humidity and regulate it through targeted heating and ventilation. This creates a pleasant and healthy living environment and even saves on heating costs. Colored comfort-level zones indicate whether the indoor air is ideal, too humid or overly dry. The max and min readings are saved and can be reset manually or automatically. The clear display can be read well even in the dark thanks to the backlight.
