TFA Thermomètre-hygromètre numérique 5.8x4.5x3.1 cm -20...+60°C

Trust is good, but 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 atmosphere. The digital display shows you the indoor temperature and humidity. If the smiley face is happy, everything is in the green zone. If its mood drops and the corners of its mouth turn down, that's your warning signal to make adjustments to 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 to 23 °C and 40 to 60% humidity. A slightly cooler temperature of 18 °C is acceptable in the kitchen, while in the bedroom, 16 to 18 °C is sufficient. However, be cautious: personal temperature perception can often be deceived by various factors, and humidity is difficult to sense. 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 is best to position or hang it centrally in 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.
