As a preliminarily test, iSOBER 200 can test 12 people per minute so testing 100 people in a row is just taking less than 9 minutes.

If there is alcohol consumed subject, for the precision test, we recommend you to use iSOBER 70 or iSOBER 90.

Residual alcohol in a used mouthpiece may affect to test result or can make false alcohol positive result. So we recommend you to use one mouthpiece per one testing.
