The hypsometer is only an instrument for determining the boiling-point, which gives one the height above the sea.
Associated words: altimetry, altimeter, hypsometry, hypsometer.
The hypsometer showed 11,070 feet above the sea; we had therefore reached a greater altitude than the Butcher's.
Mertz boiled the hypsometer when necessary to ascertain our elevation above sea-level.
After taking the reading we greedily drank the water which had been heated for the hypsometer.
An instrument sold by dealers for the measuring of heights is known as the hypsometer.
The hypsometer was not at that time an important instrument.
According to the hypsometer and our aneroid barometer we were at a height of 11,075 feet -- this was in lat.
The readings of the hypsometer gave practically the same result day after day; the ascent we were looking for failed to appear.
I took the observation for longitude and latitude, found the height by hypsometer, and took some photographs.
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.
