TFA indoor-outdoor thermometer brushed stainless steel 4.5x9x2.8cm

This timeless and clear thermometer is made of high-quality stainless steel. It is weatherproof and can be used both indoors and outdoors.

By controlling the indoor temperature, you can save on heating costs – up to 6% for a one-degree temperature reduction. And you'll simply feel more comfortable. Installed outdoors, you'll receive the outside temperature as important information for your home, garden, leisure, and work.

The thermometer is manufactured entirely in Germany. A two-point adjustment makes it particularly accurate. The capillaries are filled with a specially colored thermometer fluid. Mercury has long since been discontinued for this purpose.
