What is the purpose of the Intoxilyzer 8000 device?

The Intoxilyzer 8000 is designed specifically to analyze breath for alcohol content. This device operates on the principle of infrared spectroscopy, which allows it to detect the presence of alcohol in a person's breath. When an individual exhales into the device, it measures the amount of alcohol vapor present, which is then translated into a blood alcohol concentration (BAC) reading.

This capability is crucial for law enforcement and safety personnel who need to assess whether a driver is under the influence of alcohol without drawing blood, thus providing a non-invasive and immediate method of assessment. The focus on breath analysis sets this device apart, as it provides a quick and efficient means of gauging sobriety on roadside stops or during DUI checkpoints.

The other options mentioned do not align with the specific function of the Intoxilyzer 8000. For instance, measuring blood alcohol levels directly would involve a blood sample, which is not the method employed by this device. Recording driving habits pertains to different technologies that monitor vehicle operation rather than alcohol levels. Lastly, testing for illegal substances falls outside the scope of the Intoxilyzer 8000's purpose, as it is solely focused on alcohol detection through breath analysis.
