Which instrument measures humidity?

Which instrument measures humidity?

• A. Hygrometer
• B. Barometer
• C. pH meter
• D. Flow meter

Answer: (A)

Humidity is the amount of water vapor in the air, and a hygrometer is designed to measure that moisture content, usually reporting relative humidity as a percentage. In lab and animal care settings, knowing and controlling humidity helps keep animals comfortable and equipment functioning properly, since many processes and materials respond to moisture levels. The other instruments measure something different: a barometer gauges atmospheric pressure, a pH meter measures how acidic or basic a solution is, and a flow meter determines how fast a fluid is moving. Some devices may monitor multiple environmental factors, but when you’re specifically measuring humidity, a hygrometer is the right tool.
