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.

   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 ...

   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.

6. Psychrometrics - Wikipedia

   en.wikipedia.org/wiki/Psychrometrics

   For a given DBT there will be a particular humidity ratio for which the air sample is at 100% relative humidity: the relationship reflects the physics of water and air and must be determined by measurement. The dimensionless humidity ratio is typically expressed as grams of water per kilogram of dry air, or grains of water per pound of air ...

   As a quick refresher, humidity is the measurement of the amount of water vapor in the air. Indoor humidity should be kept between 30-50%, according to the EPA. Cleaning, doing laundry and washing ...
