What aspect of testing does the Intoxilyzer 9000 specifically measure?

The Intoxilyzer 9000 is designed specifically to measure blood alcohol concentration (BAC) through breath analysis. It utilizes infrared spectroscopy to detect specific wavelengths of light absorbed by alcohol molecules in a person’s breath. This crucial ability allows law enforcement to determine the level of impairment due to alcohol consumption at the moment of testing.

The technology is calibrated to identify alcohol content accurately, ensuring that the results contribute effectively to legal proceedings and public safety measures. The other options provided do not pertain to the function of the Intoxilyzer 9000; heart rate, carbon dioxide levels, and body temperature measurements are outside the scope of what this device is intended to assess.
