A barometer measures air pressure using a metal chamber from which some air has been removed. The most common type is the mercury barometer, where the air pressure pushes down on a pool of mercury in a glass tube to indicate atmospheric pressure.
Meteorologists use a barometer to measure air pressure. A barometer can be either an aneroid or a mercury type and helps meteorologists predict changes in the weather based on differences in air pressure.
It depends, a barometer can measure many different types of air pressure and there are different kinds of air pressure. your best bet would be to identify what type of barometer you have and simply read a dial. If you don't have a barometer and would just like to know what the maximum registered amount for high pressure is then you should consult you weather records centre. These following records i believe are the most up to date: 1085.6 mb in Mongolia. The lowest recorded air pressure is 850 mbar in Manchester, South Dakota. In theory a barometer can record any amount of air pressure depending on its size. The larger the barometer, the greater range of measurement of air pressure. Currently the worlds largest Barometer resides in the Denmark Visitor Centre. You can find more about this Barometer at: http://www.bertbolle.com/
The barometer measures air pressure. Its main usefulness is when the pressure is rising or falling. If you are in a house with a basement and the sky looks ominous and you suddenly see the gauge on the barometer decreasing, it means that the air pressure around your house has started falling fast. It also means you should get into your basement as fast as possible so you will avoid the tornado that will blow your house away. A falling barometer indicates stormy weather is coming. A rising barometer indicates fair weather is coming. With satellites and weather reports we have less need for barometers except during severe storms when we most need such reports.
Clay soil is most commonly waterlogged because its small particle size and poor drainage properties make it difficult for water to infiltrate and drain. This can lead to saturation and waterlogging of the soil, affecting plant growth and health.
Aneroid
The most commonly used barometer is the mercury barometer.However, it is not easy to transport but it gives more accurate results. Another type of barometer is Aneroid barometer which is easy to transport and handle.
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.
The first barometer that was invented was the MERCURY barometer. a mercury barometer consists of a glass tube open at the bottom end and partially filled with mercury. (:

In Chile, the most commonly used electrical outlets are Type C and Type L.
LED is a small type of light that is commonly used today.
Alternating current (AC) electricity is the most commonly used type of electricity today. It is used to power homes and businesses because it is more efficient for long-distance transmission and can easily be converted to different voltages.
Lucien Vidie, French scientist, invented the aneroid barometer in 1843.
Cheddar cheese is most commonly associated with the diet of a mouse.
Metric 6 point sockets are the most commonly used sockets today. American made vehicle used to only have standard bolt, but today they are being replaced by metric bolts like all other manufacturers.
The most popular type of cognac on the market today is VS (Very Special) cognac.
