Portable Alconsensor Test
With the advent of portable technology in recent years, law enforcement has kept with the changing times as well. The physical field sobriety tests (FST) are only one part of their capable offense against drunk driving. If a driver displays drunken behavior, police may ask the subject to breathe into a portable sensor that measures blood alcohol content.
The most famous portable alcosensor is the Breathalyzer. This instrument relies on chemical oxidation to produce the alcohol level. However, the Breathalyzer is being phased out for newer forms of breath testing using infrared spectroscopy technology.
