Important information
Threshold limits for impaired driving incapacity vary from country to country.
Independent of this, because of different tolerances to alcohol, a blood alcohol
concentration of lower than 0.2 – 0.4 ‰ for example can also impair driving and
lead to criminal culpability. In Germany, criminal prosecution and a fine can be
expected if neurological impairment is 0.30 ‰ or above.
A test with the C A 8120 will not be accepted by the police as evidence, it is
nevertheless an important indicator for you to act responsibly. The COSMOS-
ALCOHOL-TESTER was calibrated before shipment. To ensure continued correct
measurement results, it should be recalibrated every 6 months. To do this, please
send the device to you supplier.
The measuring method
Blood and breath alcohol are closely connected. Deep in the lungs, in the alveoli,
blood and breathed air are separated by a thin gas permeable membrane. The gas
exchange takes place here.
Oxygen passes to the blood and carbon dioxide, and any alcohol, passes to the
breathed air.
In order to get this air out of the depth of the lungs (alveolar air) for analysis, a
sufficient minimum volume of breathed air must be breathed out.
Only if a sufficient volume of breathed air is breathed out and this is blown with
enough strength for at least 4 seconds will a correct measurement be achieved.
