Our distinctive thermometers utilise 17th century astronomer Galileo Galileia's discovery that the density of liquids varies with temperature. Carefully weighted glass globes are suspended in a liquid-filled tube, where they sedately sink or float as the surrounding air gets hotter or colder.42cm height with Coloured Floats. Temperature Range: 16°C~28°C These fascinating instruments work on the principle that liquids change density with temperature, discovered by Italian astronomer Galileo in the 17th Century. As the liquid in the glass tube is warmed or cooled by the air around it, the colour globes rise or sink, as their relative densities vary, indicating roon temperature by the engraved brass tag on the lowest of the floating globes. 43cm.
