What is another word for mercury barometer?
Pronunciation: [mˈɜːkjʊɹi bəɹˈɒmɪtə] (IPA) 
A mercury barometer is a device used to measure air pressure, consisting of a glass tube filled with mercury. However, there are other types of barometers that can also be used to measure air pressure. Aneroid barometers use a small metal capsule to measure changes in air pressure, while a digital barometer uses electronic sensors to measure air pressure. Additionally, there are variations of mercury barometers, such as the siphon barometer, which uses a U-shaped tube and a siphon to measure changes in air pressure. Another type of mercury barometer is the fortin barometer, which has an adjustable cistern to improve accuracy. Though all of these devices are used to measure air pressure, each has its own unique advantages and disadvantages.
