A hygrometer is an instrument used to measure the amount of water vapor in air in soil or in confined spaces.

Wet and dry bulb hygrometer is an instrument which measures.

It has numerous commercial uses but the primary purpose of the device is to measure the amount of water vapor humidity in the air. A hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. Its bulb is immersed in a bottle or reservoir of liquid green at the base. Hygrometer measuring.

There are two main types of hygrometers a dry and wet bulb psychrometer and a mechanical hygrometer. By rapidly rotating both thermometers or by blowing air over the bulbs the temperature of the wet bulb thermometer is cooler than that of the dry bulb thermometer. To fully understand how to use a hygrometer it helps to know when and where you can use it a hygrometer is an essential instrument in meteorological science. You measure the humidity by comparing the readings from the two thermometers.

The other thermometer right is the wet bulb. Humidity measurement instruments usually rely on measurements of some other quantities such as temperature pressure mass a mechanical or electrical change in a substance as moisture is absorbed. Used to measure the air temperature. Wet bulb temperature is measured using a thermometer that has its bulb wrapped in cloth called a sock that is kept wet with distilled water via wicking action.

One of them left is a dry bulb thermometer and simply measures the temperature of the surrounding air like any conventional thermometer. Two mercury thermometers a cotton ball and room temperature water. The wet and dry bulb temperatures technique offers a more accurate measurement of humidity. The psychrometer q v is a hygrometer that utilizes two thermometers one wet bulb and one dry bulb to determine humidity through evaporation a wetted cloth wraps the wet bulb thermometer at its enlarged end.

A widely used device for measuring wet and dry bulb temperature is a sling psychrometer which consists of a pair of mercury bulb thermometers one with a wet sock to measure. Psychrometer definition of psychrometer by the free dictionary. Such an instrument is called a wet bulb thermometer. An instrument that uses the difference in readings between two thermometers one having a wet bulb and the other having a dry bulb to measure the.
