What accuracy range is typically expected from the Intoxilyzer 9000?

The Intoxilyzer 9000 is designed to provide precise measurements of blood alcohol concentration (BAC), and the expected accuracy range is ±0.005% BAC. This level of accuracy is crucial in ensuring that the results from the device can be used reliably in legal and disciplinary contexts. For instance, a tolerance of ±0.005% BAC means that if the device registers a BAC of 0.080%, the true BAC could realistically be between 0.075% and 0.085%. This level of precision is necessary to enforce laws related to driving under the influence and to uphold the credibility of breath alcohol testing as evidence in court cases.

Other accuracy ranges, while they may appear numerically close, would not provide the same reliability needed in legal situations. A wider accuracy range could increase the potential for false positives or negatives, thus impacting the integrity of testing methodologies in law enforcement. The showcased accuracy of ±0.005% BAC demonstrates the Intoxilyzer 9000's role as an important tool in alcohol testing and regulation.
