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.
An instrument used to determine atmospheric pressure or elevation by observing the boiling point of water or other liquids. The sensitivity of the hypsometer increases with decreasing pressure, making it more useful for high altitude work.
any of several tools or instruments designed to measure the height of trees. The clinometer is such a tool.
An instrument used to measure the heights of trees, employing geometric or trigonometric principles. | | | | E-F | | | I-K | | | N-O | | | | T-X
an altimeter that uses the boiling point of water to determine land elevation
A simple instrument, often a stick or other straight edge, used to measure the heights of trees on the basis of similar angles.
Any device used for measuring tree height.
A Hypsometer is an instrument for measuring altitude which employs the principles that the boiling point of a liquid is lowered by diminishing the barometric pressure, and that the barometric pressure varies with the height of the point of observation.
