Princíp merania vlhkomeru
In the measurement method, humidity is defined as the "quantity of the physical state". The humidity referred to in daily life is relative humidity, expressed in RH percent . In short, it is the percentage of saturated water vapor (saturated water vapor pressure) in a gas (usually air) that contains the same amount of water vapor (water vapor pressure) as its air.
Vlhkosť už oddávna úzko súvisí so životom, no ťažko sa to dá vyjadriť kvantitou. Existuje absolútna vlhkosť, relatívna vlhkosť, rosný bod, pomer vlhkosti k suchému plynu (hmotnosť alebo objem) atď.
