Question

Quizplus · Accepted Answer

A barometer is specifically designed to measure atmospheric pressure. A manometer can also be used for this purpose, but it is a more general term that refers to any instrument used to measure the pressure of a fluid in a closed system, including gases like air. Sphygmomanometers are used to measure blood pressure, while spectrophotometers and spectrometers are used to measure the absorption or emission of light by a sample, which is not related to atmospheric pressure.
