Calibrating a breathalyser is essential to ensure accurate and reliable measurements of blood alcohol concentration (BAC). Calibration is the process of adjusting the device to a standard reference point to maintain its accuracy.

Calibration is essential for all alcohol breathalysers. Just like a clock needs readjusting after a long period of use, a breathalyser must also be recalibrated to maintain accuracy.
