Analogue window thermometer with metal holder
This rotating window thermometer is mounted to the outside of a window frame with its practical metal holder. Just use the adhesive pads or the screws to put it into the right position. The mounting parts are included. 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 calibration makes it very accurate.
The capillaries are filled with a specially coloured alcohol, as the dangerous mercury is no longer used for this purpose.
