H-B DURAC Calibrated Dual Zone Elec Thermometer -50/70C (-58/158F) External, 0/50C Internal

Galileo Galilei discovered when a liquid's temperature increases, its 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. Individually packaged. Features: Decorative functional thermometer is a great conversation piece perfect for the home or office Sealed glass cylinder contains a clear liquid and several glass spheres of varying densities that individually rise or fall to indicate temperature Tag on the lowest sphere in ...
