How does the Intoxilyzer 9000 ensure non-biased readings?

The Intoxilyzer 9000 ensures non-biased readings primarily through strict calibration and adherence to standardized testing protocols. This process is critical in maintaining the integrity and accuracy of the device's measurements. Regular calibration against known standards helps to ensure that the device is responding accurately to alcohol concentration in the breath sample.

Standardized testing protocols are equally essential, as they establish consistent procedures for administering the test. This includes specific instructions on sample collection, environmental considerations, and the use of control samples to validate the equipment's performance during testing. Such measures minimize external influences and variations that could affect the results, leading to more reliable and objective readings of a subject's blood alcohol content (BAC).

The combination of accurate calibration and adherence to established protocols eliminates potential biases that could arise from the testing conditions or operator influences, thereby reinforcing the credibility of the results obtained from the Intoxilyzer 9000.
