Calibrating breathalyzers

Calibrating a breathalyzer involves adjusting the device to ensure its alcohol readings are accurate and reliable. This is done by testing the device with a standardized alcohol solution of a known concentration. If the device's measurement differs from the known value, it is adjusted accordingly. Regular calibration maintains the device’s accuracy over time, accounting for wear and environmental factors. Proper calibration is essential for fair assessments in legal settings and for personal safety, ensuring that the results truly reflect an individual's blood alcohol content.
