Alco-Sensor IV with Memory (DOT Evidential Breathalyzer)

The Alco-Sensor IV with Memory (ASIVm) is a handheld breath alcohol tester. It provides a simple, accurate and economical method of determining a subject’s breath alcohol concentration.  The evidential grade results are stored to on-board memory for serial printing or later transfer to a computer based centralized database program (sold separately).




The Alco-Sensor IV w/Memory follows an automated, software driven test protocol. Each function is displayed on an LED display which provides the operator with step-by-step instructions for fail-safe testing. The ASIVm automatically samples deep lung breath, displays the result in a three digit readout (two or four digits where required), stores the test record to memory and is capable of printing the result if an optional printer is interfaced with the instrument. The proper insertion of the mouthpiece powers the instrument ON and a mouthpiece release feature, which eliminates operator contact with a used mouthpiece, turns the instrument OFF.
