EVERYDAY SCIENCE

Detailed explanation-1: -Relative Humidity of the atmosphere is measured by the wet and dry bulb thermometer also called the Hygrometer. The hygrometer consists of two similar mercury thermometers.

Detailed explanation-2: -A hygrometer is an essential instrument in meteorological science. It has numerous commercial uses, but the primary purpose of the device is to measure the amount of water vapor (humidity) in the air.

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 hygrometer is a device used to measure humidity. Hygrometers come in both analog and digital versions, but modern, digital hygrometers are more accurate, so they are the most commonly used today. The Davis Temperature and Humidity sensor measures temperature and humidity for both inside and outside.

Detailed explanation-5: -Hygrometers that do not determine the air humidity via two thermometers are often called psychrometers. A more general term that includes all devices for measuring air humidity is hygrometer. The German Meteorological Service (DWD) uses traditional psychrometers, e.g. a fan-ventilated Assmann psychrometer .
