Analogue School Thermometer
This vivid and educational school thermometer made of beech wood is ideal for teaching, as it gives you the current temperature in three different units: Celsius, Fahrenheit and Réaumur.
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.
