The device that measures humidity is called a

Explanation:
Humidity is measured with an instrument designed to sense water vapor in the air. That instrument is a hygrometer, which directly reports how moist the air is, often as a relative humidity percentage. A psychrometer is a specific type that uses two thermometers to infer humidity, but it’s still a method for measuring humidity rather than the general term for the device. Barometers measure air pressure, and thermometers measure temperature, which are not direct measures of humidity. So the best answer is hygrometer.
