TFA Digital Thermometer-Hygrometer 4x5.5x1.5 cm -10?+60°C (30.5055.02)

With this practical little thermo-hygrometer, you can easily keep an eye on the temperature and humidity and regulate them if necessary. The maximum and minimum values are stored and displayed at the touch of a button. The thermo-hygrometer adheres to metal surfaces with two small magnets on the back. If you want to set up the device, you can use the fold-out stand. The climate comfort display classifies the comfort level of the currently measured temperature and humidity: a smiling smiley face indicates when the climate conditions are optimal. A neutral or sad face indicates moderate or poor conditions. You can choose between four different areas of application for the thermo-hygrometer: Room climate, musical instruments, turtle and humidor.
Indoor climate: Whether we feel comfortable and cozy indoors depends to a large extent on the quality of the indoor air. Controlling the indoor temperature and humidity through targeted heating and ventilation creates a comfortable and healthy living environment and even saves on heating costs. A room temperature of 19 ? 25 °C and a relative humidity of 40 ? 60 % is perceived as pleasant by most people and minimizes health risks.
Musical instruments: Musical instruments made of wood such as pianos, violins and guitars react sensitively to climatic conditions. Wood is a hygroscopic material; when humidity is high, moisture is absorbed and objects can warp. If the surrounding air is too dry, moisture is extracted and cracks appear. The optimum climate conditions for many musical instruments are 18 ? 24 °C and 45 ? 55 % relative humidity. Please check whether these values also apply to your own instrument. Important when storing musical instruments: Climatic conditions should remain at as constant a level as possible. Keep an eye on the stored maximum and minimum values and avoid large fluctuations in temperature and humidity.
Tortoise: As cold-blooded animals, tortoises kept in terrariums are dependent on sufficient heat sources. Excessively dry housing conditions favor diseases and can lead to dehydration. The conditions for the "tortoise" mode correspond to the ideal conditions for a European tortoise. During the activity phase, 25 ? 32 °C and 45 ? 65 % relative humidity are ideal. Please make sure you find out whether your tortoise species may require different conditions.
Humidor: High humidity is essential for the shelf life of cigars. For this reason, cigars are stored in a special container with an integrated humidification system, the humidor. At 65 ? 75 % relative humidity and 18 ? 22 °C, most types of cigars retain their full aroma and can be stored for years. The thermometer is powered by a standard AAA battery 1x 1.5 V (not included).
