<P>PROBLEM TO BE SOLVED: To provide an apparatus for measurement of alcohol in expiration, capable of bringing a measurement subject to keep a condition of an appropriate expiration pressure, more easily. <P>SOLUTION: The alcohol interlock system includes: an alcohol fuel cell sensor for measuring an alcohol concentration in expiratory air of a driver; an expiration pressure sensor for measuring a pressure of the expiration; a display unit for notifying the pressure of the expiration measured by the expiration pressure sensor, in a seven segment display fashion; and a CPU which brings the alcohol fuel cell sensor to measure the alcohol concentration when the pressure of the expiration is within a range of the appropriate expiration pressure. The CPU is characterized by segmenting the range of the appropriate expiration pressure into a plurality of zones and bringing the display unit to notify the pressure of the expiration by using the zones (steps S266, S270, S274 and S278). <P>COPYRIGHT: (C)2010,JPO&INPIT |
