What is the purpose of quality control checks on the Intoxilyzer 9000?

The purpose of quality control checks on the Intoxilyzer 9000 is to ensure proper device function and accuracy. This is crucial because the reliability of blood alcohol concentration (BAC) measurements depends on the precision and functionality of the instrument. Regular quality control checks help identify any malfunctions or deviations in performance that could lead to inaccurate test results.

These checks typically involve using standardized solutions with known alcohol concentrations to confirm that the device is reading accurately. If discrepancies are detected during these checks, the device can be recalibrated or serviced as necessary, thus maintaining the integrity of the testing process.

Quality control is a critical component of operating the Intoxilyzer 9000, as it directly impacts the validity of the results obtained from each breath test conducted. Understanding this importance helps ensure compliance with legal and procedural standards for breath alcohol testing in Texas.
