If an alcohol thermometer utilizes a combination of ethanol, toluene, and pentane, its lower temperature range may be extended to measure temperatures down to as low as −200 °C (−328 °F). [3] However, the measurement temperature range c. −200 °C to 78 °C, is highly dependent upon the type of alcohol used.
Alcohol thermometers, infrared thermometers, mercury-in-glass thermometers, recording thermometers, thermistors, and Six's thermometers (maximum-minimum thermometer) are used in meteorology and climatology in various levels of the atmosphere and oceans.
A cryometer is a thermometer used to measure very low temperatures of objects. Ethanol-filled thermometers are used in preference to mercury for meteorological measurements and can measure temperatures in the range of −38 to 70 °C (−36 to 158 °F). Their main physical limitation is the freezing and boiling point of the liquid used.

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic compound with the chemical formula CH 3 CH 2 OH. It is an alcohol , with its formula also written as C 2 H 5 OH , C 2 H 6 O or EtOH, where Et stands for ethyl .
Simply place your bottle of vodka, rum, tequila—any spirit with more than 40% alcohol by volume (ABV) or 80 proof—in the freezer. A properly-sealed bottle of high-proof alcohol should last for ...
Old thermometer in a pharmacy in Vienna, showing room temperature by Reaumur scale. Réaumur and Celsius scale on thermometer. Private collection, central Europe. The Réaumur scale (French pronunciation: [ʁeomy(ː)ʁ]; °Ré, °Re, °r), also known as the "octogesimal division", [1] is a temperature scale for which the melting and boiling points of water are defined as 0 and 80 degrees ...
At the first rest stop, their usual one, a flyer pinned to the bulletin board outside the unheated bathrooms lists suicide hotline numbers: “If you are depressed please Avoid drugs and alcohol. Talk to someone, express your feelings.” The temperature drops from 6 degrees to 3 to 1. A road sign reads “Pass With Care.”
