ABSTRACT:
A device for measuring the absolute value of the density of salts in an atmosphere, which comprises an airtight water tank containing super pure water; a means for supplying super pure water to the airtight water tank; a means for bubbling a predetermined quantity of air in the atmosphere into the super pure water being provided in the airtight water tank; a means for exhausting the super pure water in the airtight water tank after the bubbling; a sodium ion analyzer for measuring the density of sodium ions in the exhausted super pure water; and a means for introducing the outside air to the bubbling means in accordance with the pressure difference between the inside and the outside of the water tank.
