SYPHON BAROMETER
The basic construction, unchanged since Torricelli's experiment in 1643, is a glass tube about
three feet long, closed at one end, filled with mercury, and inverted with the open end
immersed in a cistern of mercury. With the cistern surface exposed to atmospheric pressure,
the height of the mercury column varies with that pressure. Mercury barometers may be
classified into three groups according to their construction: cistern barometers, siphon
barometers, and weight barometers.
