To demonstrate how a bimetal thermometer works;

adheres to window panes, so the outside temperature can be easily read from the inside,

the bimetal spiral is clearly visible through the transparent back plate;

measuring range: -40 ... +50 °C,

diameter of the bimetal spiral: 20 mm,

disk diameter: 150 mm
