Analogue hygrometer with a thermometer

The large needle gives the level of humidity as a percentage and the small needle gives the temperature.
If you want to dehydrate fruit or cold meats or on the contrary, leave your saucissons to sweat in a hot, damp room: the hygrometer will give you the information you need.
Measuring the level of humidity in the outside air can also give you precious information about your harvest.
Inside, you can determine the best place to preserve your fruit, for example, without it drying out.
Works without batteries.
