Carbon Monoxide Detector Proper Placement

That I will agree with , lol. We go on a lot of these calls, we go and check for co when the alarm goes off. All meters are a bit diffrent and sound at different levels. Some are better then others. Many just accumulate co and go into alarm when there saturated and give a false positive. Those are rhe cheaper ones, the good ones take samples and purge themselves. Usually at the time when they first sound around 30 ppm the co is more concentrated around the device thats causing the problem. The levels are not constant throughout a room. So if your stove is producing co, the levels will be higher at the stove, and less everywhere elese in the room. And the readings dissapate from the stove out in all directions. 30 ppm, is a lower number and really will not cause any health issues, even with long time exposure. So its set to go off way before there are problems. If it makes you happy, you can put it up higher, but it really dosen't matter.
