Met AI
The instrument uses two identical thermometers: a dry-bulb thermometer and a wet-bulb thermometer.
The wet bulb is cooled by water evaporation, resulting in a lower temperature than the dry bulb.
The temperature difference between the two thermometers (the psychrometric difference) is used to calculate the relative humidity based on tables or formulas.
