/ɑlˈtɪmədər/

Origin: A borrowing from Latin. Perhaps also partly formed within English, by compounding. Etymons: Latin altimeter ; alti- comb. form, -meter comb. form².

Etymology: Originally < post-classical Latin altimeter instrument for measuring height (1540 or earlier; also quoted by Du Cange from Papias (11th cent.); compare altimeter , adjective (1532 in gnomon altimeter , 1535 in scala altimetra , or earlier)) < classical Latin alti- alti- comb. form + -meter -meter comb. form². In later use (in sense 2) perhaps directly < alti- comb. form + -meter comb. form². Compare Middle French altimètre (adjective) (of a scale) designed to measure vertical height (1562), French altimètre (noun) instrument for measuring vertical extents or angles (1803), instrument which indicates the altitude above sea level of the bearer (1922), and also Spanish altimetro, adjective (late 16th cent.; 19th cent. as noun). N.E.D. (1884) gives the pronunciation as (æ̆lti·mĭtəɹ) /ælˈtɪmɪtə(r)/.

1. An instrument for measuring vertical extents or angles (cf. altitude n. 1, 4). Now rare.

?1768 T. Whittell Treat. Dendrometer i. 19 Move the index downwards, until you see, through the sights, the bottom of the tree cut by the horizontal wires; and there note the feet and inches marked by the index upon the altimeter below the point of sight or horizontal line.

1821 Ann. Philos. New Ser. 2 442 I may describe a simple portable altimeter I have contrived, that Mr. Trimmer and myself have some thoughts of making.

1852 W. Beschke Mem. U.S. Congr. & Govt. 56 Instead of being ‘altimeters’, to measure vertical angles, our telescopes must be planimeters, to measure horizontal angles.

1910 Mines & Minerals June 671/1 The transit has folding sights, a clinometer and altimeter, gives vertical angles to single degrees and slopes in feet per 100 horizontal, or centimeters per meter.

2. An instrument which indicates the altitude above sea level reached, as when flying or climbing a mountain.Some modern altimeters provide additional information, such as rate of climb or change in air pressure.radio altimeter: see the first element.

1904 Knowledge Feb. 17/1 We have received from Messrs. Newton and Co. a list of their optical and other scientific instruments. Among their novelties is the Altimeter, which has been made to supply a want that has been felt among kite flyers and military balloonists.

1907 Sci. Amer. 26 Oct. 290/2 The engraving shows the altimeter with the cover of the case removed. The instrument is, in reality, a recording aneroid barometer.

1918 ‘B. Cable’ Air Men o' War 179 His altimeter showed him to be a bare couple of hundred feet up.

1927 C. A. Lindbergh ‘We’ viii. 133 The fog..was 800 to 900 feet high, according to my altimeter.

2004 High Mountain Mar. 37/3 We were climbing and reached the height of the pass according to our altimeters, but the slope still fell away to the north.
