Detailed explanation-2: -The rain gauge is an instrument that is used for measuring rainfall. The rain gauge is also known as an udometer, pluviometer, or an ombrometer. It measures the rain in a localized area.

Detailed explanation-3: -A rain gauge (also known as an udometer, pluviometer, ombrometer, and hyetometer) is an instrument used by meteorologist (scientist who study weather) and hydrologists ( scientists who study water) to gather and measure the amount of liquid precipitation over a predefined area, over a period of time.

Detailed explanation-4: -Hygrometer is used to measure the rainfall.

Detailed explanation-5: -Explanation: Rain gauge is used by the meteorologists for measuring the amount of precipitation over the time period considered. The instrument gives the best result when it is placed in an open area.
