What is the primary function of the Intoxilyzer 9000?

The primary function of the Intoxilyzer 9000 is to measure the blood alcohol concentration (BAC) of an individual through breath analysis. This device works by detecting the amount of alcohol present in a person’s breath, which correlates to the amount of alcohol in their bloodstream. The technology relies on infrared spectroscopy to identify and quantify the ethanol levels in the breath sample.

This functionality is critical in law enforcement and public safety, particularly in situations where drinking and driving is a concern. The process is quick and non-invasive, making it a valuable tool for officers to assess an individual's level of intoxication effectively and adhere to legal standards related to driving under the influence.

Other options, while related to bodily assessments, do not pertain to the function of the Intoxilyzer 9000. Measuring body temperature and analyzing blood samples fall outside the scope of breath analysis, and assessing carbon monoxide levels is not a function of this particular device. Hence, the focus remains squarely on breath alcohol concentration measurement as the clear purpose of the Intoxilyzer 9000.
