COMPONENTS AND FUNCTIONS

Instrument Operating Components

Mouthpiece (23-0120-00)

The mouthpiece is a critical portion of the sample assembly and specifically designed to be
used with the Alco-Sensor FST.
The cross section is a "D" shape which helps orient the mouthpiece when placing it on the
instrument. By inserting the closed end of the mouthpiece into the mouthpiece channel, and
then rotating the shaft of the mouthpiece downward, the flat side of the mouthpiece and the two
holes on the underside of the mouthpiece will naturally align and attach to the appropriate ports
on the Alco-Sensor FST.
Use only mouthpieces manufactured or approved by Intoximeters. The design of the
mouthpiece can affect both the analytical process and/or damage the instrument. Using
unapproved mouthpieces can void the instrument warranty and make it impossible for
Intoximeters to support test results generated while using these unapproved parts.

Drink Sniffer/Mouthpiece (23-0190-00)

The Drink Sniffer/Mouthpiece attachment is designed to improve the ASFST's ability to test the
'headspace' above a beverage for the presence of alcohol.

Passive Sample Cup (23-0130-00)

The Passive Sampling Cup is designed to help automatically collect an air sample while a
subject is blowing in the direction of the instrument. For best passive results have the subject's
mouth about two inches from the top of the cup, while the subject is blowing into the cup.
