Bel-Art Products, 62000-0600, DURAC 64/80F Galileo Thermometer, 330mm

Galileo Galilei discovered when a liquid's temperature increases, it's density decreases. His findings inspired these unusual and interesting thermometers with colorful spheres which rise and fall to indicate temperature. Galileo thermometers are crafted of glass and individually calibrated to achieve an accuracy of 1°C (2°F). The tag on the lowest sphere in the top group indicates the current temperature. Individually packaged.
