Overview
The operating principle of this equipment is based on the wet- and dry-bulb system, which is
considered to be the most stable method for measuring relative humidity.
There are two temperature sensors; one is called a wet-bulb sensor that the bulb is wrapped with a
wick and the other is called a dry-bulb sensor. The wick of the wet-bulb is moistened with water.
When the moisture evaporates, heat is taken and the temperature of the bulb falls. In this situation,
there is a relationship ("Sprung formula") between the latent heat of vaporization and the vapor
pressure in the atmosphere where measurements are being made. The relative humidity can be
obtained from this relationship.
In this equipment, a motor-driven forced ventilation device is incorporated in the sensor head to
suck up air from the lower air intake tube (vent) through the temperature sensing section. This
ventilation system quickly stabilizes the readings and has been used as a humidity standard device
for a precise measurement.
This equipment is used not only in the meteorological observation but also in the places that strict
humidity control is required as a standard instrument for relative humidity.
