Detailed explanation-1: -A psychrometer is a device used to measure the humidity of air. It accomplishes this by comparing the difference in temperature between a dry thermometer bulb and a wet thermometer bulb that has lost some of its moisture through evaporation.

Detailed explanation-2: -A psychrometer measures relative humidity, and an anemometer measures wind speed. Meteorologists use the data from these instruments to make weather forecasts. A surface report describes a set of weather measurements made on Earth’s surface. Weather variables are measured by a weather station.

Detailed explanation-3: -A sling psychrometer can be used to find relative humidity, which is expressed as a percentage. It is computed by multiplying the amount of moisture in the air at a given temperature, dividing by the maxi-mum amount of moisture the air could contain at that same temperature, and then multiplying the quotient by 100.

Detailed explanation-4: -A psychrometer measures the ambient air temperature (dry bulb temperature) and the wet bulb temperature. From the dry bulb and wet bulb temperature the dew point is calculated. The dew point is the temperature at which moisture in the air will start condensing.

Detailed explanation-5: -Sling psychrometer. Dew point can be calculated using the air temperature and a relative humidity value, which is measured using something called a sling psychrometer.
