CALIBRATION CALIBRATION Calibration (also known as adjustment) is the verification of the breathalyzer results with the results given by the standard of the measurement unit. During calibration, the sensor of the device is adjusted with the software so that the alcohol content in the blown air is the same on the display of the breathalyzer as the value on the reagent bottle in the calibrator. Each device has an individually selected calibration interval resulting from its design and purpose. Usually, when it comes to personal breathalyzers, they should be calibrated (depending on the technology) every 3, 6 or 12 months. The calibration frequency depends on the model of the breathalyzer and the technology of the sensor. Breathalyzers with an electrochemical sensor are calibrated less often than models with a semiconductor sensor. Detailed information on the period and frequency of calibration in individual models can be found in their instructions. Another important signal for calibration are the results that differ significantly from reality, e.g. 0,5 per mille despite the lack of alcohol consumption. Remember that regardless of the recommendations in the operating manual, the breathalyzer should be calibrated whenever you have doubts about its indications.
