an instrument that measures atmospheric pressure
An instrument for measuring atmospheric pressure
Anything used as a gauge or indicator.
Origin: From βάρος.
an instrument for determining the weight or pressure of the atmosphere, and hence for judging of the probable changes of weather, or for ascertaining the height of any ascent
A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. Pressure tendency can forecast short term changes in the weather. Numerous measurements of air pressure are used within surface weather analysis to help find surface troughs, high pressure systems, and frontal boundaries.
Chambers 20th Century Dictionary
bar-om′et-ėr, n. an instrument by which the weight or pressure of the atmosphere is measured, and changes of weather, or heights above sea-level, indicated.—adj. Baromet′ric.—adv. Baromet′rically.—n. Barom′etry. [Gr. baros, weight, metron, measure.]
The Standard Electrical Dictionary
An apparatus for measuring the pressure exerted by the atmosphere. It consists, in the mercurial form, of a glass tube, over 31 inches long, closed at one end, filled with mercury and inverted, with its open end immersed in a cistern of mercury. The column falls to a height proportional to the pressure of the atmosphere from 30 to 31 inches at the sea level. The "standard barometer" is a height of the mercury or of the "barometric column" of 30 inches or 760 centimeters, measured from the surface of the mercury in the cistern. The column of mercury is termed the barometric column. Above it in the tube is the Torricellian vacuum. [Transcriber's note: More accurately, 29.92 inches of mercury or 14.696 PSI.]
