Two-thirds of their lifetime, people spend at least indoors. Whether we feel comfortable and cozy there largely depends on the quality of the indoor air. Rooms that are too humid promote mold growth, but excessively dry air is also harmful to health, affecting pets, plants, wooden floors, and antique furniture. This functional thermo-hygrometer is an ideal measuring instrument for monitoring the indoor climate. You can easily keep an eye on temperature and humidity and regulate them through targeted heating and ventilation. Colored comfort zones indicate whether the indoor air is ideal, too humid, or too dry. This way, you can create a pleasant and healthy living environment while even saving on heating costs. Maximum and minimum values are stored and can be reset manually or automatically. The backlight allows the clear display to be read easily even in the dark. For some TFA wireless weather stations, the thermo-hygrometer can also be used as a wireless transmitter.
