You would use a mercury manometer
You will need to use a carbon scrubber device to capture co2 under atmospheric pressure.
mercury manometer
If you mean, who needs to know what the atmospheric pressure is, that would be meteorologists. If you mean, who makes use of the atmosphere, that would be everybody who breathes.
To measure pressure in the air. Meteorologists use them (weather people) a barometer is used for measuring pressure,the units for measuring pressure include atm,pascal,torr,mm of hg,bars.
A barometer is used to measure atmospheric pressure. It can also measure altitude!
Below atmospheric pressure.

isobars are a measure of atmospheric pressure. variations in atmospheric pressure basically cause weather - high pressure vs low pressure, etc.
Usually the instrument used is called a barometer- which could be a closed end manometer or an aneroid barometer.An altimeter actually also measures atmospheric pressures - but for a different purpose.

Gravity and atmospheric pressure.
The same as anyone else. Use it to find out the atmospheric pressure
An atmospheric condenser operates naturally at atmospheric pressure (1.013bar). A vacuum condenser operates at pressures below atmospheric and will use some sort of pump to provide a vacuum.
