Any instrument for measuring the humidity, or water vapour content, of a gas (usually air). A wet and dry bulb hygrometer consists of two vertical thermometers, with one of the bulbs covered in absorbent cloth dipped into water. As the water evaporates, the bulb cools, producing a temperature difference between the two thermometers. The amount of evaporation, and hence cooling of the wet bulb, depends on the relative humidity of the air.
A hygrometer is important because it shows the humidity of the atmosphere. For a hygrometer to work though it has to placed outside.

THE HYGROMETER IS A INSTRUMENT USED TO MEASURE HUMDITY.
There is no difference, a psychrometer is a type of hygrometer.
A device that measures humidity is called a hygrometer.
i used a hygrometer to measure the humidity outside
The least count of a hygrometer typically refers to the smallest change in humidity that can be measured by the device. This value is determined by the precision and resolution of the hygrometer's sensors and display, and can vary depending on the specific model and design of the hygrometer.
a hygrometer is important because without it we wouldn't know the relative humidity in the air
The hygrometer was invented in the year 1670 by a man named Francesco Folli. Leonardo da Vinci was said to have built the first crude hygrometer in the 1400's.
