Product specification

Sufficient light is enough to power TFA's "ECO SOLAR" thermo-hygrometer. This environmentally-friendly device is solar-powered and ideal for monitoring the indoor climate.
At least two thirds of a person’s lifetime are spent indoors. Whether we feel well and comfortably at home depends to a great extent on the quality of the indoor air. Rooms that are too humid favour mould growth, but overly dry air can be harmful to our health and pets, plants, wooden floors and antique furniture will also suffer.
With the "ECO SOLAR" thermo-hygrometer you can easily keep an eye on temperature and humidity and regulate it with targeted heating and ventilating. The two measured values are displayed alternately. The max. min. memory with manual reset allows the observation of peak values over a self-selected period of time. The large display makes reading easier.
The linear, sleek design of the "ECO SOLAR" thermo-hygrometer is not only aestetically pleasing, but also good for nature.
