E Coleman reached Athabasca Pass in 1893, the elevations of Athabasca Pass and Mount Brown were measured using an aneroid
barometer and boiling point thermometer.
From here, Aneroid
Mountain looms from a wall of stripey red-brown cliffs on the horizon.
Then there were, and are, round aneroids
, banjo round aneroids
, pocket aneroids
, altimeters and desk barometers.
Their website boasts of "an incredible variety of weather predictors, from conventional mercury and aneroid
Whether the equipment is aneroid
, mercury, or electronic, it should be regularly inspected and validated.
Hazlitt adds that this application is rather unique for bellows, "We've seen bellows used for aneroid
functions, pressure compensation, seals, flexible couplings and self-locating electronic connectors, but this is one of the few as a mechanical manipulator.
In coastal Queensland Jack used Admiralty Charts, filling in the land areas with dead reckoning, star sights, bearings to coastal headlands, and aneroid
barometer altitude readings.
DuraShock[TM] Integrated Aneroid
Sphygmomanometer--Shock-Resistant Blood Pressure Monitor
devices provide a high degree of accuracy when supported by a regular maintenance program.
New devices use diodes and other current technology to supplant the century-old standard mercury and aneroid
sphygmomanometers, while retaining the auscultatory technique.
The simplest and least expensive device--an aneroid
sphygmomanometer--consists of a blood pressure cuff connected by a rubber tube to a dial that registers pressure.
Measurements should be taken preferably with a mercury sphygmomanometer, a calibrated aneroid
manometer, or a validated electronic device.
