How much ‰ 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 from ‰ to mg/l can be done in the following way: x ‰ = x/2.27 mg/l (for example: 0.5‰ = 0.22mg/l because 0.5/2.27 = 0.22)

How much time between drinking and blowing?

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 per mille BAC alcohol concentration is blown through an alcohol tester, the device is adjusted to ensure that the correct reading of 0.5 per mille is displayed on the screen.
It is important to calibrate alcohol testers periodically to maintain accuracy.

Like any other analytical instrument, alcohol testers must be calibrated to ensure their accuracy. Calibration benefits the 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 model and usage, but it is recommended that AlcoSafe/AlkoSure/AlcoFind/Dräger alcohol testers be calibrated every 300/500 tests or at least once a year (whichever comes first) (depending on model) . Also, if a large number of “high positive” (high alcohol concentration) values ​​are measured by the device, it may be necessary to perform the calibration much earlier than normally recommended.
