Word of the day: aneroid barometer

The word of the day is aneroid barometer:

  1. a device for measuring atmospheric pressure, often specially calibrated for use as an altimeter, consisting of a box or chamber partially exhausted of air, having an elastic top and a pointer to indicate the degree of compression of the top caused by the external air.

Compare mercury barometer


"Stevedores hauled the Jeannette's weapons on deck...  Next came the navigational and scientific equipment: chronometers, hydrometers, ozonometers, magnetometers, aneroid barometers, transits, sextants, pendulums, zenith telescopes, microscopes, test tubes, Bunsen burners, theodolites."
