Q.  What is meant by the term "breathalyzer?"

A.  "Breathalyzer" can refer to any instrument that measures a person's breath to determine its alcohol content and then converts that amount to a blood alcohol content ("BAC") measurement. The term was originally used many decades ago to refer to Smith & Wesson's particular brand of breath testing device. Susequently, like the terms Kleenex and Xerox, it has become synonymous with any breath testing device of this type. The State of Arkansas has adopted the use of the Intoximeter EC/IR II as its evidentiary breathalyzer.
