Instrument Used To Measure Humidity Of The Atmosphere

By calibration and calculation these measured quantities can lead to a measurement of humidity.

Instrument used to measure humidity of the atmosphere.

A hygrometer is an instrument used to measure the amount of water vapor in air in soil or in confined spaces. A hygrometer is an instrument used to measure relative humidity. 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. Instrument for measuring the relative humidity of the atmosphere weather balloon a balloon released into the atmosphere that carries a package of instruments to record data about temperature air pressure and humidity.

A psychrometer uses two thermometers to measure relative humidity. The pce 313a air humidity meter measures relative humidity and temperature and can be used in the air conditioning sector. Just about everyone knows that it refers to the amount of moisture in the air but you re a lot less likely to find someone who understands the different humidity measurement units. There are two main types of hygrometers a dry and wet bulb psychrometer and a mechanical hygrometer.

10 00 8 used new offers 4 4 out of 5 stars 21 842. Humidity is the measure of the amount of moisture in the air. A psychrometer is an example of a hygrometer. One measures the dry bulb temperature and the other measures the wet bulb temperature.

Of the two main types of barometers mercury and aneroid aneroid are more widely used. Humidity can be a complex topic to understand. A hygrometer is a weather instrument used to measure the amount of humidity in the atmosphere. A barometer is a weather instrument used to measure air pressure.

Italian physicist evangelista torricelli is credited with inventing the barometer in 1643. The aneroid barometer is used to measure atmospheric pressure as well as altitude it consists basically of an evacuated flat cylindrical closed metal box with corrugated flexible faces that are kept from collapsing together by a spring as the external pressure varies the distance between the flat faces alters and a pointer is operated such an instrument is calibrated by comparison with a mercury barometer it is also used as an altimeter. Acurite 00613 digital hygrometer indoor thermometer pre calibrated humidity gauge 3 h x 2 5 w x 1 3 d. In this article we ll go over the five different units that you need to learn and we ll explain why relative humidity is the most useful.
