Single-use test to determine the level of alcohol in exhaled air.
Changes colour when a chemical reaction occurs in the presence of alcohol above the legal limit (0.5 g/l).

Blow slowly without excessive force until the pouch is completely full (a valve prevents the air from escaping).
Tear off the capsule from the glass tube to start the test.
Insert the balloon mouthpiece into the test unit until reaching the stopper.
Slowly and completely empty the balloon through the test unit.
The results are ready one minute after the exhaled air enters the tube.
If the green colour passes the fine line, the blood alcohol level is above 0.5 g/l.
Complies with standard NFX - 20 - 702
