The PAS IV uses passive alcohol test technology to sniff the breath of a person or the interior of a car for the presence of alcohol. The PAS IV is designed to detect alcohol with or without the subjects participation. The operator positions the PAS IV flashlight close to a subjects face and asks them to talk or blow at the device. A fan inside the device pulls in a portion of the subjects breath to analyze for alcohol. Yellow and red lights come on to indicate the presence of alcohol.
Fuel Cell Sensor Specific for Alcohol
The P.A.S. IV uses a fuel cell to detect alcohol. Fuel 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 IV can have a high degree of confidence that positive results with the PAS IV are due only to alcohol.
Battery Charge Doubles as Storage Rack
The PAS IV flashlight comes equipped with a rechargeable NiMH battery pack and a battery charger that operates on AC or DC power. The PAS IV snaps securely into the battery charger cradle. When mounted in a car the charger also secures the device for ready, convenient access as it charges the batteries.
