  2. Dew point - Wikipedia

    en.wikipedia.org/wiki/Dew_point

    A relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water. When the moisture content remains constant and temperature increases, relative humidity decreases, but the dew point remains constant. [9]

  3. Humidity - Wikipedia

    en.wikipedia.org/wiki/Humidity

    By comparison, thermal comfort standard ASHRAE 55 requires systems designed to control humidity to maintain a dew point of 16.8 °C (62.2 °F) though no lower humidity limit is established. [46] Water vapor is a lighter gas than other gaseous components of air at the same temperature, so humid air will tend to rise by natural convection. This ...

  4. Wet-bulb temperature - Wikipedia

    en.wikipedia.org/wiki/Wet-bulb_temperature

    The wet-bulb temperature is the lowest temperature that may be achieved by evaporative cooling of a water-wetted, ventilated surface.. By contrast, the dew point is the temperature to which the ambient air must be cooled to reach 100% relative humidity assuming there is no further evaporation into the air; it is the temperature where condensation (dew) and clouds would form.

  7. Hygrometer - Wikipedia

    en.wikipedia.org/wiki/Hygrometer

    In residential settings, hygrometers are used to assist in humidity control (too low humidity can damage human skin and body, while too high humidity favors growth of mildew and dust mite). Hygrometers are also used in the coating industry because the application of paint and other coatings may be very sensitive to humidity and dew point.

  8. Water activity - Wikipedia

    en.wikipedia.org/wiki/Water_activity

    Dew point hygrometers work by placing a mirror over a closed sample chamber. The mirror is cooled until the dew point temperature is measured by means of an optical sensor . This temperature is then used to find the relative humidity of the chamber using psychrometrics charts.
