Incompetent Breath Test
Lee Forrester writes [AIR 15:6]:
I, too, am a student of the history of breath testing equipment. Tyrone Amphew’s letter (AIR Vents 15:4) about the famous Montague Laboratory experiments is very, very misleading, to say the least. I have a copy of the entire photo, enclosed here.
What Amphew showed was just a piece of it. A glance is enough to show any engineer at least six reasons why the Montague device would have been unreliable. I challenge your readers to list all six. It is a challenge I issue to my students every spring in my Engineering for Alcohol Detection for Forensic Detection Laboratories” course, which is among the most popular courses I teach, as any of my former students will be happy to tell you.
