How many ‰ or mg/l is legally allowed?

This varies from country to country in Belgium the rule is max. 0.5‰ or 0.22 mg/l unless as a professional driver (such as bus driver, etc.) then it is 0.2‰ or 0.088 mg/l. Converting ‰ to mg/l can be done as follows: x ‰ = x/2.27 mg/l (for example: 0.5‰ = 0.22mg/l because 0.5/2.27 = 0.22)

What affects the alcohol content in your body?

The extent to which alcohol is absorbed into your body is influenced by many factors such as gender, age, weight, stomach contents, health condition, fatigue, etc. Every individual is different and reacts differently, even when the same amount of alcohol is consumed. It can even vary from day to day.

Calibration is checking and adjusting the accuracy of an alcohol tester by comparing the displayed results with a known value. For example, a known 0.5 promille BAC alcohol concentration is blown through an alcohol tester, the device is adjusted to ensure that the correct reading of 0.5 promille is displayed on the screen.
It is important to calibrate alcohol testers periodically to maintain accuracy.

Like any other analytical tool, alcohol testers need to be calibrated to ensure their accuracy. Calibration benefits aging of the sensor and other critical components. We strongly recommend that you calibrate your alcohol tester once a year or sooner.

How often to calibrate

It varies depending on the model and its use, but AlcoSafe/AlkoSure/AlcoFind/Dräger breathalysers are recommended to be calibrated every 300/500 tests or at least once a year (whichever comes first) (depending on the model) . Also, if a large number of “high positive” (high alcohol concentration) values ​​are measured by the device, it may be necessary to perform calibration much earlier than normally recommended.
