Analogue Window Thermometer
This window thermometer is attached to the window frame outside with its holder. Just use adhesive film to mount it into the right position. Now you can easily read the outside temperature from the comfort of your living room.
The thermometer is entirely manufactured in Germany. A 2-point adjustment makes it very accurate.
The capillaries are filled with a specially coloured thermometer liquid. The use of mercury in thermometers has been forbidden for several years.
