Calibration is crucial for the proper functioning and accuracy of any breathalyser, including the Dräger Alcotest 4000.

This device is designed to measure blood or breath alcohol concentration (BAC/BrAC) in individuals, making it an essential tool for personal users. Calibration ensures that the breathalyser provides precise and consistent readings.

The accuracy of a breathalyser, like the Alcotest 4000 is dependent on its ability to measure breath alcohol content correctly. Over time, factors such as environmental conditions, wear and tear, and exposure to various substances can affect the instrument’s sensitivity and performance. Calibration involves adjusting the device to a standard reference point, typically a known concentration of alcohol vapour. This process helps eliminate any deviations or inaccuracies that may have developed during regular use. Calibration, therefore, acts as a safeguard against potential errors, ensuring that the breathalyser remains a trustworthy tool for assessing alcohol impairment.

Manufacturers like Dräger provide specific guidelines regarding the frequency and procedures for calibration to meet these standards. Adhering to these recommendations ensures the device’s accuracy.
