This instrument is the 19th century equivalent of GPS, Victorian men (it was nearly alwaysmen) would purchase this sort of instrument before embarking on an adventure, probably involving hill climbing, ballooning ormountaineering. This instrument could not only be used to predict the weather (rain, sun etc.)but was also able to indicate yourheight abovesea level.
To measure your height you rotate theouter chapter ringuntil the hand is aligned with thezero(assuming you are at sea level), then as you climb, the hand moves due to thefall in air pressure.
The word 'compensated' indicates that this barometer automatically adjusts the reading for changes in temperature, thereby giving a more accurate reading.
