The aneroid barometer most commonly used today would be the tiny quartz transducers built into GPS units, sports wrist watches and the like.
These would outnumber Mercury column types, and other aneroid ones.

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.

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.
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. (:
nowadays there are many types of barometer. some are automatic and some are manual. so, please name which type of barometer's structure you want to know.

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.
