What component of the Intoxilyzer 9000 primarily affects its accuracy?

The accuracy of the Intoxilyzer 9000 is primarily influenced by calibration and maintenance procedures. Regular calibration ensures that the device provides reliable and consistent readings by adjusting any potential discrepancies in its sensors or measurement systems. If the device is not properly calibrated, it may produce inaccurate blood alcohol concentration (BAC) results, which could lead to erroneous legal implications.

Maintenance procedures, such as routine servicing and component checks, also play a critical role in ensuring the Intoxilyzer 9000 functions correctly. Any wear or malfunction in the equipment, if not addressed, could lead to errors in measurement. Thus, adherence to proper calibration and maintenance protocols is essential for the device's accuracy and reliability in intoxication assessments.

The other factors listed, such as lighting conditions, type of breath sample, and the monetary value of the device, can impact testing conditions and operational efficacy but do not fundamentally affect the device's inherent accuracy as calibration and maintenance do.
