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.
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.
The two main types of barometers are mercury barometers, which use a column of mercury to measure air pressure, and aneroid barometers, which use a small metal box that expands or contracts with changes in pressure to indicate atmospheric pressure.
There are two types of barometers, Mercury barometers and then Aenroid barometers.
Mercury barometers and aneroid barometers are the most commonly used types today. Mercury barometers use a column of mercury to measure atmospheric pressure, while aneroid barometers use a small, flexible metal box to detect changes in pressure.

mercury barometers and aneroid barometers both measure air pressure.
Historical, both thermometers and barometers have used mercury.
They are more portable and can be used for airplane equipment
The two main types of barometers are mercury barometers and aneroid barometers. Mercury barometers use a column of mercury in a glass tube to measure atmospheric pressure, while aneroid barometers use a sealed metal chamber that expands and contracts with pressure changes. Both types are used to predict weather changes, with mercury barometers being more precise and aneroid barometers being more portable and durable.

Many do, but not all. Most barometers that people would have in their homes are aneroid barometers, which don't contain any mercury.
Mercury is commonly used in barometers due to its high density and ability to accurately measure air pressure. However, due to its toxicity, alternatives such as water, oil, or electronic sensors are often used now.
