Abstract
PURPOSE: To easily and accurately measure the alcohol, which is dissolved in water, by blowing air into water at a lower temperature than 25°C so that the dissolved alcohol trapped as gases may be detected with the use of a semiconductor element of metal oxide.
CONSTITUTION: Celan air is blown from a blow pipe 3 into a liquid 2 to be tested, which is contained in a container 1 and which can dissolve alcohol at a lower temperature than 25°C, and is made to rise in the liquid 2 in the form of bubbles through a lower end porous member 4. In this meanwhile, the dissolved alcohol is transferred as gass into the air. Then, this air is sucked by a constant rate suction pump 10 and is guided into a measuring box 7 through a collecting pipe 5 and a water trap 6 so that is brought into contact with a semiconductor detecting element of a metal oxide such as SnO2 or ZnO. The concentration of dissolved alcohol is metered by measuring the variation in the resistance. Incidentally, it is sufficient that the depth of the pipe 3 into the water be about 2 to 3 cm, and the invitation of the measurement error due to the variation in the water temperature is compensated with the use of a thermostat 9.
