Question

Quizplus · Accepted Answer

A manometer is specifically designed to measure the pressure of gases in laboratory settings. A barometer is used to measure atmospheric pressure, while a sphygmomanometer is used to measure blood pressure in medical settings. A spectrophotometer and spectrometer are used to measure the properties of light and electromagnetic radiation, respectively, and are not used to measure gas pressure.
