  2. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    Specific humidity (or moisture content) is the ratio of the mass of water vapor to the total mass of the air parcel. [15] Specific humidity is approximately equal to the mixing ratio, which is defined as the ratio of the mass of water vapor in an air parcel to the mass of dry air for the same parcel.

  3. 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.

  4. Lifting condensation level - Wikipedia

    en.wikipedia.org/wiki/Lifting_condensation_level

    The lifting condensation level or lifted condensation level (LCL) is the height at which the relative humidity (RH) of an air parcel will reach 100% with respect to liquid water when it is cooled by dry adiabatic lifting.

  6. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    If all the other factors influencing humidity remain constant, at ground level the relative humidity rises as the temperature falls; this is because less vapor is needed to saturate the air. In normal conditions, the dew point temperature will not be greater than the air temperature, since relative humidity typically [5] does not exceed 100%. [6]

  7. Humidity indicator card - Wikipedia

    en.wikipedia.org/wiki/Humidity_indicator_card

    Maximum humidity indicator cards are irreversible, thus indicating the highest level of humidity experienced by cargo during its voyage, regardless of current (potentially lower) humidity levels. They provide a clear, unmistakable means of determining if goods have been exposed to damaging humidity levels during their journey.

  8. Humidifier - Wikipedia

    en.wikipedia.org/wiki/Humidifier

    A properly installed and located hygrostat should be used to monitor and control humidity levels automatically, or a well-informed and conscientious human operator must constantly check for correct humidity levels. A humidity below 50% can prevent water condensation on building materials. [1] A dehumidifier can be used to balance the humidity.
