  2. Hygrometer - Wikipedia

    en.wikipedia.org/wiki/Hygrometer

    A hygrometer is an instrument which measures the humidity of air or some other gas: that is, how much of it is water vapor. [1] Humidity measurement instruments usually rely on measurements of some other quantities such as temperature, pressure, mass, and mechanical or electrical changes in a substance as moisture is absorbed.

  3. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    A hygrothermograph for humidity and temperature recording Hygrometer for domestic use, wet/dry psychrometer type Thermo hygrometer displaying temperature and relative humidity. A device used to measure humidity of air is called a psychrometer or hygrometer. A humidistat is a humidity-triggered switch, often used to control a humidifier or a ...

    en.wikipedia.org/wiki/Moisture_meter

    Measuring water leakage in exterior wall with Trotec T660 Moisture Measuring Device, using dielectric measurement method (indicative). Moisture meters are measuring instruments used to measure the percentage of water in a given substance, as physical properties are strongly affected by moisture content and high moisture content for a period of time may progressively degrade a material.

    In this example the humidity ratio is 0.0126 kg water per kg dry air. Determining the effect of temperature change on relative humidity: For air of a fixed water composition or moisture ratio, find the starting relative humidity from the intersection of the wet and dry bulb temperature lines. Using the conditions from the previous example, the ...

  7. Meteorological instrumentation - Wikipedia

    en.wikipedia.org/wiki/Meteorological_instrumentation

    A hygrometer measures the relative humidity at a location, which can then be used to compute the dew point. Radiosondes directly measure most of these quantities, except for wind, which is determined by tracking the radiosonde signal with an antenna or theodolite.

    [23] [24] This is the same unit commonly used to measure the amount of moisture in the air, also known as the absolute humidity. [25] The SI unit used to measure particulate emissions and absolute humidity is mg/m 3. [23] [25] One grain per cubic foot is approximately 2288 mg/m 3. [note 2]
