  • Apparatus for measuring the alcohol percentage in the breath of an examinee
    Patent number: 4161875
    Abstract: Apparatus for measuring the alcohol percentage in the breath of a person by blowing the breath into an airtight chamber enclosing a gas detector of the type of which the electric resistance changes upon exposure to alcohol vapor. The breath is introduced into the chamber in such manner that it does not directly strike the gas detector, so that a cooling of the gas detector by the air flow is avoided. Thus, the resistance change of the gas detector is substantially exclusively dependent on the alcohol percentage in the breath, whereby a very accurate measurement is obtained.
