What should the target value be for the alcohol level in the dry gas standard used for calibration?

The appropriate target value for the alcohol level in the dry gas standard used for calibration is 0.08. This value is significant because it corresponds to the legal blood alcohol concentration (BAC) limit established in many jurisdictions, including Georgia, for driving under the influence (DUI) offenses.

Using 0.08 as the target alcohol level ensures that the Intoxilyzer 9000 is calibrated to accurately reflect the physiological effects of alcohol at this commonly enforced limit. Calibration at this level helps maintain the precision and reliability of the testing equipment when it is used in actual DUI investigations.

The other values suggested are not typically used for calibration in this context. They either fall below the commonly enforced legal limit or exceed the 0.08 standard, which is tailored for specific legal and enforcement purposes. Hence, using 0.08 aligns with legal standards and public safety initiatives.
