The barometer was invented by Evangelista Torricelli
Torricelli invented a device for measuring air pressure called a mercury barometer. It consists of a glass tube filled with mercury placed in a dish of mercury. The height of the mercury in the tube changes with variations in atmospheric pressure.
As you climb a mountain, the atmospheric pressure decreases with altitude, causing the mercury level in the barometer to decrease. This is because there is less air pressing down on the mercury in the barometer as you ascend, leading to a lower reading.
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.
Mercury barometer precaution
To reset a mercury barometer after travel, first ensure the barometer has settled to room temperature. Then, carefully check for any air bubbles in the mercury column and gently tap the barometer to release any trapped air. Finally, adjust the mercury column height to match the current atmospheric pressure by turning the adjustment screw if needed.
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. (:

A mercury barometer.
The first barometer was a mercury barometer invented by Evangelista Torricelli in 1643. It consisted of a glass tube filled with mercury inverted in a dish of mercury. As atmospheric pressure changed, the mercury level in the tube would rise or fall, allowing for the measurement of air pressure.
The device that Torricelli invented for measuring air pressure is called a barometer. It works by balancing the weight of the atmosphere with the weight of a column of mercury in a glass tube.

Evangelista Torricelli invented the first mercury barometer in 1643 and stated that the height of the column of mercury in the barometer is directly proportional to the atmospheric pressure at that location. This discovery led to the understanding that changes in atmospheric pressure can help predict weather patterns.
barometer has mercury inside it .
In Florence, Italy in 1644, Evangelista Torricelli built the first mercury barometer, at the Florentine Academy.
A Mercury barometer is used to measure atmospheric pressure.
Evangelise Torricelli invented the mercury barometer in the 1600s. It was very accurate, but it was clumsy to move and had to stay upright. If humans hadn't invented the aneroid barometer, you would see big mercury barometers in all types of transportation.
