What are the uses of hygrometer?
Answer:
A device that is used to measure the moisture content of the air is called a hygrometer. The relative humidity is measured in the air by a hygrometer. Relative humidity is represented as a proportion; it represents the amount of humidity in the air, or vapour, to the maximum amount of humidity that the air can possibly contain. On a scale of zero to 100, relative humidity is evaluated, the greater the value, the more moisture content in the air.
