How to use hypsometer in a sentence
Mertz boiled the hypsometer when necessary to ascertain our elevation above sea-level.The Home of the Blizzard | Douglas Mawson
According to the hypsometer and our aneroid barometer we were at a height of 11,075 feet -- this was in lat.
The hypsometer is only an instrument for determining the boiling-point, which gives one the height above the sea.
The hypsometer showed 11,070 feet above the sea; we had therefore reached a greater altitude than the Butcher's.
The readings of the hypsometer gave practically the same result day after day; the ascent we were looking for failed to appear.

Scientific definitions for hypsometer
An instrument used to determine land elevation by observing the atmospheric pressure as measured by the change in the boiling point of a liquid, usually water. Liquids boil at progressively lower temperatures as the atmospheric pressure decreases, and since atmospheric pressure decreases with altitude, the temperature at which the liquid boils is an indicator of the atmospheric pressure at that location and hence of the location's altitude.
