How often must the Intoxilyzer 9000 be calibrated?

The Intoxilyzer 9000 must be calibrated every month or after any repairs to ensure accurate readings of blood alcohol concentration (BAC). Calibration is a vital process because it verifies that the instrument is functioning correctly and providing reliable measurements. Routine calibration helps to account for any potential drift in the electronic sensors or inaccuracies that could arise from regular use, environmental factors, or alterations that might occur during maintenance or repairs.

Calibration on this schedule allows law enforcement agencies to maintain the integrity of breath alcohol testing, thereby ensuring that legal standards are met and that the results are dependable in court proceedings. This frequency supports the device’s reliability and upholds the evidentiary value of the tests conducted with it. Regular checks, such as these, are crucial in maintaining the device's precision necessary for enforcing DUI laws and protecting public safety.
