Mercury barometer is used for measuring atmospheric pressure.
Because atmospheric pressure changes with distance above or below sea level, a barometer can also be used to measure altitude.

Historical, both thermometers and barometers have used mercury.
Please refer to the related links for an article about the uses for mercury.
There are two types of barometers, Mercury barometers and then Aenroid barometers.
mercury barometers and aneroid barometers both measure air pressure.

Mercury and aneroid barometers.
Aneroid barometers are advantageous because they are safer to use compared to mercury barometers which contain toxic mercury. Aneroid barometers are also more portable, durable, and do not require periodic maintenance like mercury barometers do. Additionally, aneroid barometers are less prone to breakage and are not affected by temperature changes like mercury barometers.
The two common types of barometers are mercury barometers, which use the height of mercury in a column to measure atmospheric pressure, and aneroid barometers, which utilize a flexible metal membrane to detect and measure pressure changes without using liquid. Digital barometers are also becoming more popular, using electronic sensors to measure pressure.
Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any mercury.
An aneroid barometer does not contain mercury. Instead, it uses a small, flexible metal box called an aneroid cell to measure air pressure changes. Aneroid barometers are safer and more portable than mercury barometers.
There are a number of uses for the natural resource mercury. These include making thermometers, barometers, as well as diffusion pumps.
Scientists use mercury barometers and aneroid barometers to measure atmospheric pressure. Mercury barometers measure pressure by balancing the weight of mercury against atmospheric pressure, while aneroid barometers use a flexible metal box to detect pressure changes.
