Mouthpiece ‐ The mouthpiece is a critical portion of the sample assembly and specifically
designed to be used with the Alco‐Sensor FST®. Inserting the closed end of the mouthpiece into
the mouthpiece channel, with the flat side of the mouthpiece downward, and pressing down
will place the mouthpiece into position. The two holes on the underside of the mouthpiece will
naturally align and attach to the appropriate ports of the Alco‐Sensor FST®.
