Pffttt! AlcoSense TruTouch is just a gimmick. Why would anybody pay 300 pounds/week for it is mind-boggling. Notice that there aren’t any real specs in the website. Ethanol is one of the simplest organic molecules and the NIR spectrum is composed of just overtones and combination bands for only 2 types of bonds, C-H and O-H, which are present in many, many molecules in the human body. I can guarantee that anybody can win a lawsuit against any entity using that device against them.
