Which of the following produces a continuous record of atmospheric pressure?

An aneroid barometer produces a continuous record of atmospheric pressure. An aneroid barometer consists of a small, flexible metal box called an aneroid cell, which is made of a partially evacuated capsule. Changes in atmospheric pressure cause the capsule to expand or contract, which is then recorded by a needle on a dial. Unlike a mercury barometer, an aneroid barometer is portable and can be used to measure atmospheric pressure at different locations. Therefore, it is an ideal instrument for producing a continuous record of atmospheric pressure over a period of time.
