Preferred Label : psychrometric hygrometer;
IUPAC definition : Instrument by which the relative humidity of the atmosphere may be determined. It
is generally composed of two temperature sensors, one of which measures the temperature
of the air; the other sensor is moistened with water and senses the cooling due to
evaporation of water. The temperature difference between the two sensors is a function
of relative humidity; sometimes referred to as a 'wet-and-dry bulb' thermometer.;
