Here is the solution:
Analogue hygrometer 44.1007
Create a comfortable indoor climate for your home! The small and practical hygrometer measures the humidity in your rooms and is quickly and easily attached to most surfaces with the adhesive pad.
Once the value is outside the comfort level of 40 to 60% for a prolonged period, you can respond to it.
Since a room air that is too humid promotes the emergence of dangerous mould; but a room air that is too dry can have an adverse effect on our well-being in several respects: skin and respiratory system will suffer and infections, allergies and asthma symptoms can worsen.
Pets, plants, wooden floors, antique furniture, musical instruments and books also need the right climatic conditions.
The hygrometer is entirely manufactured in Germany.
