Thermometer vs. Cryometer — What's the Difference?

A thermometer is a device that measures temperature or a temperature gradient (the degree of hotness or coldness of an object). A thermometer has two important elements: (1) a temperature sensor (e.g.

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 of minimum temperatures and can be used down to −70 °C (-94 °F).

An instrument for measuring temperature, especially one having a graduated glass tube with a bulb containing a liquid, typically mercury or colored alcohol, that expands and rises in the tube as the temperature increases.

A thermometer capable of measuring very low temperatures.

An apparatus used to measure temperature.

A thermometer used at very low temperatures.

An instrument for measuring temperature, founded on the principle that changes of temperature in bodies are accompanied by proportional changes in their volumes or dimensions.

A thermometer for the measurement of low temperatures, esp. such an instrument containing alcohol or some other liquid of a lower freezing point than mercury.
