TFA 30.1037 ECO Solar - digital thermometer

Sufficient light is enough to power TFA's "ECO SOLAR" thermometer, as this environmentally friendly device is solar-powered and it’s ideal for checking the temperature in your home. Controlling the room temperature is an important factor for a comfortable and healthy living environment and it helps save energy. Even one degree less temperature can bring up to 6% reduction in heating costs. With the stored highest and lowest values, the settings of the radiators can be monitored well. The linear, sleek design of the "ECO SOLAR" thermo-hygrometer is not only aestetically pleasing, but also good for nature.
