Answer 1

Answer:

Hygrometer

Explanation:

A hygrometer is an instrument used to measure the amount of water vapor in air, in soil, or in confined spaces.

Answer 2

The answer is hygrometer

The amount of water vapor in the air is measured with a hygrometer in meteorological science. Hygrometers of various major types are used to measure humidity.

Mechanical hygrometers rely on the idea that organic materials, especially finer ones like human hair and goldbeater's skin (ox gut), expand and contract in reaction to humidity. In a mechanical hygrometer, the spring moves the needle on the dial as the hair element contracts and expands.

Electrical hygrometers track variations in electrical resistance caused by humidity changes in a thin coating of lithium chloride or a semiconductor device.

Therefore the device that is used to measure humidity is hygrometer
