An instrument for measuring heights by observation of barometric pressure; esp., one for determining heights by ascertaining the boiling point of water. It consists of a vessel for water, with a lamp for heating it, and an inclosed thermometer for showing the temperature of ebullition.

[Gr.] Hypsometry, the measurement of heights; the word generally implies that the measurement is effected not by a triangulation, but by a portable instrument such as an aneroid or mercurial barometer. In an Hypsometer, advantage is taken of the fact that the boiling point of water is lowered when the atmospheric pressure is reduced, to effect the measurement of heights by observing the temperature of the boiling point of water.
