Trust is good, control is better. A thermo-hygrometer is the best friend of a comfortable climate and the warning sign that alerts you when something is wrong with the environment. The digital display shows you the indoor temperature and humidity. If the smiley face is smiling at you, everything is in the green zone. If its mood drops and the corners of its mouth turn down, that’s your warning signal to adjust the room climate by actively heating and ventilating. The goal is to create a pleasant atmosphere. Studies show that most people feel most comfortable in rooms with temperatures between 20 and 23 °C and humidity levels of 40 to 60%. A slightly cooler temperature of 18 °C is acceptable in the kitchen, while 16 to 18 °C is sufficient for the bedroom. But be careful: your personal temperature perception can often be deceived by various factors, and humidity is difficult to sense anyway. The thermo-hygrometer sends you clear, objective signals, helping you save on heating costs and detect the risk of mold due to high humidity. With a slim size of 45 x 58 mm, the digital thermo-hygrometer is almost inconspicuous, regardless of where you place it. It’s best to position or hang it in the center of the room. A spot directly by the window, near the heater, or behind a curtain is less suitable. The small device is powered by a CR2032 battery, which is included in the package.
