How frequently must the Intoxilyzer 9000 be calibrated?

The Intoxilyzer 9000 must be calibrated at least once every 31 days or after a specified number of uses to ensure its accuracy and reliability. This routine calibration is essential because it helps to maintain the instrument's precision when measuring blood alcohol concentration. Without regular calibration, the device's readings could become inaccurate over time due to factors such as environmental changes, component wear, or accumulated usage, which could compromise the integrity of test results.

Adhering to this calibration schedule also aligns with legal standards and best practices in alcohol testing, ensuring that results are defensible in court and can be trusted by law enforcement and judicial systems. Regular calibration helps to uphold public safety by ensuring that impaired drivers can be accurately identified and dealt with appropriately, thus reducing potential accidents caused by driving under the influence.
