[ther-mom-i-ter]
–noun
an instrument for measuring temperature, often a sealed glass tube that contains a column of liquid, as mercury, that expands and contracts, or rises and falls, with temperature changes, the temperature being read where the top of the column coincides with a calibrated scale marked on the tube or its frame.

Origin:
1615–25; thermo- + -meter


ther⋅mo⋅met⋅ric [thur-muh-me-trik] , ther⋅mo⋅met⋅ri⋅cal, adjective

n.  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.

thermometer 
1633, from Fr. thermomètre (1624), coined by Jesuit Father Leuréchon from Gk. thermos "hot" (see thermal) + metron "measure" (see meter (2)). An earlier, Latinate form was thermoscopium (1617). The earliest such device was Galileo's air-thermometer, invented c.1597.

thermometer   (thər-mŏm'ĭ-tər)  Pronunciation Key 
An instrument used to measure temperature. There are many types of thermometers; the most common consist of a closed, graduated glass tube in which a liquid expands or contracts as the temperature increases or decreases. Other types of thermometers work by detecting changes in the volume or pressure of an enclosed gas or by registering thermoelectric changes in a conductor (such as a thermistor or thermocouple).
