Summary:PURPOSE:To blow air into a specimen stably and to make it possible to measure the concentration of alcohol from the specimen directly and continuously by blowing the air into the specimen through an inner tube having a branching part provided with an opening regulating valve, and measuring the concentration of the alcohol in the air rising up as bubbles. CONSTITUTION:Air is blown into a specimen 30 containing alcohol through an inner tube 20 having a branching part 24 provided with a blowing regulating valve 25 stably with a air blowing pump 21. The sample 30 is surrounded with an outer tube 10. The air containing alcohol rises up in the form of bubbles from the specimen 30. The air reaches a sensor 40. Thus, the concentration of the alcohol contained in the specimen can be detected directly, continuously and accurately.
