The individual units that make it up are atoms. I think there was some mix up in nomenclature in one of yesterday's threads. That much chemistry I remember as I approach senility in my old age. And, I am a chemist. In lieu of factual literature regarding its specific gravity compared to air, I would at least lower the CO meter to the level of the head of the person working in the area. I have mine on the floor...that must mean that way back when, when I still had all of my faculties, I must have known that CO was heavier than air.... One thing I do remember--but it is of no value here--is that Argon is much more heavier than air. One time I filled an open tub full of Argon so I could manipulate some Lithium metal. The Argon stayed there for a long time without mixing with the air layer on top of it. I could tell this because the shiny Lithium metal stayed protected from the oxygen in the air above the tub, and did not discolor by getting an oxide on its surface. I deduced from this that the Brownian Motion theory was over-blown (that is a pun, think about it) Perhaps as important as whether you put your CO detector on the floor or at nose height, is that you should remember to test it once in a while for battery perfomance...
