Interviewer: Let’s talk about the breath test machine used in New Jersey for people suspected of DWI. Did you say it is called the Alcotest?
Carl Spector: It is called an Alcotest, 7110 MK III-C. Actually, that is the full name of the Alcotest machine used here in New Jersey.
Interviewer: For people who have not seen them, what does this machine look like?
Carl Spector: Well, it kind of looks like there is a keyboard; almost like an old typewriter. It is like a keyboard that you see separate from your computer. There is a box, and then there is a stalk that comes from it that you blow into.
Every time the police ask somebody to blow into it, they put a mouthpiece on it. The police are supposed to change the mouthpiece between each blow for each person. So not only do you get your own mouthpiece, but you have to get a mouthpiece for each test that you take.
Furthermore, New Jersey requires two blows, two samples, in order to get one accurate result.
