ALKOHOLANDEDREKTSSIMULATOR FOR KALIBRERING AV ANDEDREKTSANALYSATOR

摘要

A breath sample, having a fixed known alcohol content, is useful for calibrating or checking the performance of an alcoholic breath analyzer. Such a standard alcoholic breath sample may be simulated by blowing non-alccoholic breath through an elongated enclosure maintained at a given temperature and containing alcohol vapor continuously generated from an abosrbent material impregnated with an alcohol-water solution. The breath produced at the enclosure's outlet will constitute a simulated breath sample having a known alcohol concentration.
