TFA 12.3022.01 - Wall thermometer

This black plastic thermometer with silver embossed scale is weatherproof and can be used indoors or outdoors.
By controlling the indoor temperature, you save on heating costs – up to 6%, with just one degree of temperature reduction. And you simply feel better.
When installed outside, you get the outdoor temperature as invaluable information for the home, garden, leisure and work.
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.
