Barometer vs. Hygrometer: What's the Difference?
Edited by Huma Saeed || By Sawaira Riaz || Updated on October 6, 2023
A barometer measures atmospheric pressure, while a hygrometer measures humidity levels.
Key Differences
A barometer is an instrument that measures the atmospheric pressure, essential for forecasting weather and determining altitude. It operates based on the principle that the pressure exerted by the atmosphere affects the height of a column of liquid. A hygrometer, on the other hand, gauges the amount of moisture in the air, or humidity. This is crucial in weather forecasting, and it aids in maintaining the right humidity levels in various environments, providing comfort and preventing material degradation.

Barometers come in various forms, including mercury, aneroid, and electronic, each employing different methods to assess atmospheric pressure. A hygrometer also exists in different types like psychrometers, dew point hygrometers, and capacitance hygrometers, each using distinctive techniques to determine air moisture content.

Barometers and hygrometers are vital instruments in meteorology. The barometer's readings are indispensable for predicting weather changes, with falling pressure indicating bad weather and rising pressure suggesting fair weather. Conversely, a hygrometer’s readings enable the anticipation of precipitation levels, providing insights into whether the atmosphere is humid or dry.
