Thank you for purchasing Alcovisor® products. Please read this instruction
carefully before using the products and follow the instructions when you are
using the product.
Points to Remember
1. There must be an interval of at least 20 minutes after alcohol has been
taken into the mouth. Residues of alcohol in the mouth may give false
measurements. Such residues may be left by aromatic drinks,
mouthwash, medicines and drops, as well as by belching and vomiting.
Rinsing out mouth with water or non-alcoholic drinks do not substitute for
an interval.
2. Some foods and even “non-alcoholic” drinks may contain traces of alcohol,
which will affect the test result through a “mouth alcohol” effect. To
prevent this, wherever possible, ensure that a delay of about 20 minutes
has elapsed since taking anything by mouth – even medicines which may
contain alcohol. Even a glass of water prior to the test will cool the mouth
and dilute the saliva, temporarily reducing the amount of alcohol in the
breath, and, consequently, the instrument reading. A delay of at least two
minutes should take place between the time of last smoked and the test.
