The Intoximeter 3000 and the four minute fallacy

R C Denney

    Summary
    This summary is machine-generated.

    Breathalyzer clock inaccuracies do not invalidate Lion Intoximeter 3000 results. Studies show that minor clock time deviations do not affect breath alcohol measurements within normal tolerances.

    Area of Science:

    • Forensic Science
    • Analytical Chemistry

    Background:

    • The Lion Intoximeter 3000 is a device used for measuring breath alcohol content.
    • A claim suggests that clock inaccuracies exceeding four minutes invalidate its measurements.

    Purpose of the Study:

    • To scientifically evaluate the claim regarding clock time validity for the Lion Intoximeter 3000.
    • To determine if clock deviations impact the accuracy of breath alcohol measurements.

    Main Methods:

    • Simulated breath alcohol samples were used for testing.
    • Measurements were taken with the Intoximeter 3000 clock set at various times.

    Main Results:

    • Breath alcohol values remained within normal tolerances regardless of clock time variations.

  • The study found no technical basis for the claim of invalidation due to clock error.

    • Conclusions:

    • The claim that Lion Intoximeter 3000 breath alcohol values are invalid due to clock errors over four minutes is technically incorrect.
    • Clock time accuracy within the tested parameters does not affect the reliability of breath alcohol measurements.
