They were known as the But both of these barometers had their problems, not the least of which was keeping the mercury or water in its container. Barometer will show you air pressure, hygrometer will show humidity and thermometer – a real temperature. (For other ways of describing this drop in pressure with elevation visit the So if we drove around the country with a portable or auto barometer, otherwise known as an altimeter, we would see the elevation change on the dial as we climbed a hill and drove down the other side, reflecting the changes in air pressure with height.
