P.A.S Vr Passive and Direct Alcohol Testing Device
The P.A.S Vr passive and direct alcohol testing device has a switch, which allows an operator to toggle from passive alcohol testing mode to direct breath alcohol testing mode. An operator can use the passive testing mode without mouthpieces and screen large numbers of people for the presence of alcohol on their breath. The operator can then switch to direct alcohol testing mode and use a mouthpiece to administer a direct breath alcohol test to determine the intoxication level of an individual.
Passive alcohol testing without a mouthpiece
In the passive mode the P.A.S Vr. “sniffs” the breath of a person for the presence of alcohol. To perform a test the operator presses the Start button and the subject blows at the P.A.S Vr. from a distance of several inches. A fan inside the device pulls in a portion of the subject’s breath to analyze for alcohol. There is no operating cost when testing in the passive mode because the passive mode does not require mouthpieces.
DOT breath alcohol screening in Direct Test Mode
The Department of Transportation (DOT) has approved the P.A.S Vr. as an Alcohol Screening Device (ASD), when used in the direct testing mode. In direct testing mode the subject blows into a mouthpiece attached to the P.A.S Vr. Colored lights labeled in increments of 0.02% BAC light up to indicate alcohol levels up to 0.08% BAC.
Fuel Cell sensor specific for alcohol
The P.A.S Vr. uses a fuel cell to detect alcohol. Fuels cell sensors are typically used in top-of-the-line evidential breath alcohol testers because of their ability to detect low amounts of alcohol and because they are specific to alcohol. That means operators using the P.A.S Vr can have a high degree of confidence that positive results with are due only to alcohol.
