This analog thermometer made of oak can be used both indoors and outdoors. The large scale makes it easy to read. By monitoring the indoor temperature, you can save on heating costs – up to 6% with a one-degree temperature reduction. And you will simply feel more comfortable. When mounted outdoors, it provides the outside temperature as important information for home, garden, leisure, and work. The thermometer is completely manufactured in Germany. A 2-point calibration makes it particularly accurate. The capillaries are filled with a specially colored thermometer liquid.
