What instrument is used to measure Humidity?

Humidity is the amount of water vapor in the air, and the instrument used to measure that is a hygrometer. A hygrometer can be a simple device that changes with moisture—like one that uses a material that expands when damp—or a modern electronic sensor that detects changes in electrical properties as humidity shifts. That’s why it’s the appropriate tool for measuring humidity. The other instruments measure different things: a hydrometer gauges the density or specific gravity of liquids, a thermometer measures temperature, and a barometer measures atmospheric pressure.
