What is the primary function of the Intoxilyzer 9000?

The primary function of the Intoxilyzer 9000 is to analyze breath samples for alcohol. This device is specifically designed to measure the concentration of alcohol in a person's breath, which is a common method used in law enforcement to assess whether individuals are operating vehicles under the influence of alcohol. By calculating the blood alcohol content (BAC) based on the sample provided, the Intoxilyzer 9000 plays a critical role in DUI enforcement and public safety.

While options related to blood tests, heart rate, and drug detection might involve other types of testing equipment or procedures, they do not pertain to the core purpose of the Intoxilyzer 9000. The device's technology is specialized for breath analysis, allowing for the rapid and non-invasive assessment of a person's alcohol consumption.
