The present invention relates to an apparatus for measuring respiratory alcohol having a sample collector (1), the breath sample can be introduced into the sample collector through the sample inlet (2) from the test subject. The apparatus is provided with a measuring unit 9 having a sensor 16 disposed therein, the sensor being supplied with at least a portion of the respiratory sample supplied into the sample inlet 2, the sensor Generates a measurement signal based on the alcohol content contained in the breath sample. In addition, a control and evaluation unit 4 is provided, the control and evaluation unit detecting the alcohol content of the respiratory sample based on the measurement signal and sending a signal related to the result to the output unit 5 The output unit provides information on the respiratory alcohol content of the respiratory sample. The technical solution described is that the sample collector 1 and the sample inlet 2 are adapted for contactless inflow of the respiratory sample, the sample inlet proceeding at least partially within the sample collector 1. A main flow channel 10 is connected, and at least a portion of the respiratory sample supplied into the sample inlet 2 is supplied from the main flow channel to the sensor 16 at least temporarily through the measuring gas channel 21. And the main flow channel is opened to the perimeter 7 through the outlet behind the measuring gas channel 21 in the flow direction, and at least one additional between the sample inlet 2 and the outlet of the main flow channel 10. A discharge opening 6 is provided, characterized in that a part of the respiratory sample introduced into the sample inlet 2 through the discharge opening is discharged to the periphery 7.본 발명은 샘플 컬렉터(sample collector)(1)를 구비한 호흡 알코올 측정용 장치에 관한 것으로, 상기 샘플 컬렉터 내로 피실험자로부터 샘플 유입구(2)를 통해 호흡 샘플이 유입될 수 있다. 상기 장치에는, 그 내부에 센서(16)가 배치된 측정 유닛(9)이 제공되어 있고, 상기 센서에는 상기 샘플 유입구(2) 내로 공급된 상기 호흡 샘플의 적어도 일부가 공급될 수 있으며, 상기 센서는 상기 호흡 샘플 내에 함유된 알코올 함량을 기초로
