Atmospheric pressure is commonly measured using a barometer. A mercury barometer measures pressure by the height of a mercury column in a glass tube, while an aneroid barometer uses a flexible metal box to detect pressure changes. Both types of barometers provide a numerical value in units such as millibars or inches of mercury.
no disadvantage
the mercury barometer
Aneroid barometers usually look like a clock. A compact round cylinder with a glass front and a dial with pointer. Unlike mercurial barometers there is no need for a long case. Aneroid types use a small, collapsible, sealed metal can, to detect changes in pressure. The minute deformity of the can, is amplified by levers to turn the dial. all this can be held in a small instrument case, the size of a wall clock.
Mercury Barometer

One statement to accurately describe a difference between a mercury barometer and an aneroid barometer is that a mercury barometer is a closed tube containing mercury. An aneroid barometer is a closed, flexible container of gas.
Usually no difference at all. They can both move a pointer around a circular scale. The scale can be calibrated in both Inches of Mercury (InHg) or Millbars (Mb). An aneroid system can lend itself more easily to a digital display.
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.
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. (:
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.
Two advantages of an aneroid barometer over a mercury barometer are that aneroid barometers are generally more portable and do not pose a risk of mercury exposure if broken, making them safer for handling. Additionally, aneroid barometers do not require the use of toxic mercury, which is better for the environment.
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
mercury has a sudden fall and then the barometter measure it and when i mean by fall i mean air pressure so yeah it's cool I knoe it doesn't make sense but Im just writing this anyway. Even though it's pure glorius silly you know what. I PUT THAT WORD BUT THEY WON'T LET ME POST THIS STUPID ANSWER
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.
A mercury barometer works by, measuring the height of a column of mercury in a sealed tube, supported by the atmospheric pressure.An aneroid barometer measures the amount of distortion of a sealed metal can, due to changes in atmospheric pressure. The equivalent column of mercury supported by a mercury barometer, can then be calibrated in mmHg by comparison.Both instruments do the same job and can be calibrated in Millibars or mmHg, or both.
