Mercury Barometer Type of barometer that measures changes in atmospheric pressure by the height of a column of mercury in a U-shaped tube which has one end sealed and the other end immersed in an open container of mercury.

The height of this level is then used as a measure of atmospheric pressure relative to the surface level of the mercury in the container.
