Why does Mercury stay in the barometer?
A barometer is a closed-system vacuum that allows the mercury to expand with changes in temperature and pressure.

A barometer.
What instrument is used to measure air pressure?
There are several options depending on the type of air pressure being measured:In the 1800's ships used a weather glass - a simple barometer - to measure changes in air pressure.To measure atmospheric (ambient air) pressure, a barometer is used. (It may be either an aneroid or a Mercury type of barometer.)For tires, it's a tire pressure gauge.In industrial processes and boilers the gauge is frequently called a manometer.For pressure vessels it is a Bourdon gauge.
What is air pressure at Denver Colorado?
Air pressure is measured in different ways. Two common ones are PSI (pounds per square inch) or a barometer which measures in column inches of mercury. As we know the barometer goes up and down with weather so the air pressure goes up and down. The highest barometer reading ever recorded is about 32 inches or just over 15.6 PSI. The lowest barometer reading ever recorded was 25.69 in the middle of a hurricane so this is not typical but equates to about 12.5 PSI. These are all sea level readings. So we need an average, or normal. The standard is a barometer of 29.92 which equates to about 14.7 PSI, again being a sea level reading. With that standard the pressure at Denver is 12.1 PSI or a barometer of about 24.63. At this pressure water boils at about 202F instead of 212F.
What is the instrument used to determine air pressure is called?
