Glassic Gifts is the ONLY manufacturer of Galileo Thermometer currently on the market with an instant read temperature gauge printed on the outside of the glass. This innovation in Galileo Thermometer design removes the need to examine small metallic tags inside the glass. The temperature can now be read from across the room, quickly and easily! Additionally, this unit displays temperatures in both Fahrenheit and Celsius from (60˚F - 88˚F / 16˚C - 30 ˚C).

 What is a Galileo Thermometer and how do I read it?

 A Galileo Thermometer is a sealed glass column containing multiple liquid filled orbs. As the temperature changes, these orbs rise and fall to indicate the current ambient temperature (within the range of 60˚F - 88˚F / 16˚C - 30˚F). The Easy Read Galileo Thermometer features a graduated temperature gauge printed on the side of the glass. To read the thermometer, observe the void in the multi colored orbs. Whatever temperature is centered in the void, will denote the current temperature of the liquid inside the cylinder (the photos of this listing are showing a temperature of 80˚F / 26˚C). If the void is not directly over one number, the temperature is between the two numbers partially in the void. This item is finished with a hand process that creates a varying finished height, which may be slightly higher or shorter than the stated height.

How does it work?

Inspired by the finding of Galileo Galilei, these high quality glass thermometers demonstrate how temperature affects density and buoyancy. Each glass orb is partially filled with liquid to achieve a precise weight. A metal counterweight for each temperature is hung from the bottom of the orbs. As the temperature changes, the density of the liquid inside each orb changes, causing it to rise or fall within the column. Each thermometer is individually calibrated to achieve an accuracy of 2°.

IMPORTANT INFORMATION ABOUT THIS PRODUCT: Your sealed Galileo thermometer is filled with a common mineral-based, ozone friendly solvent (paraffin oil). In case of breakage, keep away from any ignition sources as it is highly flammable. Ventilate area immediately and absorb the liquid with disposable towels. Wash hands with soap and water. Potential eye irritant! In case of ingestion contact your local poison control center immediately. Be sure to use care when cleaning to avoid injury. This item requires no special disposal procedures and is made entirely of Earth friendly materials!
