Dual Testing Modes: Passive and Direct
With a flip of a switch the operator can toggle the PAS Vr. to perform passive alcohol testing or traditional direct breath alcohol testing. The operator uses the passive mode without mouthpieces to screen large numbers of people for the presence or absence of alcohol. The operator can then switch to direct mode using mouthpieces to determine the intoxication level of those individuals with alcohol on breath.
Passive testing without a Mouthpiece
In the passive mode the PAS 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 PAS 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 Screening in Direct Test Mode
The Department of Transportation (DOT) has approved the PAS Vr. as an Alcohol Screening when used in the direct mode. In direct test mode the subject blows into a mouthpiece attached to the PAS 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 PAS 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 that operators using the PAS Vr can have a high degree of confidence that positive results with the PAS Sentry are due only to alcohol.
