What portable alcohol breathalyzer do you recommend?

Answer by  Valentine62 (2131)

I have found that there is only one that I would recommend and that is Alco Mate Premium. This one does not have to be calibrated about every six months. The sensor module snaps out and a new one snaps in. No more packing your breathalyzer and shipping back to the manufacturer for re-calibration.

The different alcohol breathalyzers work in different ways. Some meause alcohol by completing a circuit. Some actually use chemical reactions to detect alcohol. All are pretty good. Try the Accu-check line (I've used the 2000 series but there are others.
