WebIt consists of a glass column with mercury and inches markings on it. The top end of the tube is closed, and the bottom end is rested in a cup containing mercury known as a cistern. To increase the accuracy, these barometers are corrected for ambient temperature and the local value of gravity. WebThe two traditional barometers are the Torricellian and aneroid. The simplest one is the tall closed tube standing upside down in the bath of mercury. This liquid rises partly up the tube a bit similar to the thermometer, for measuring the temperature. We use the mercury in barometers, as it is more convenient than the water.
