A resounding yes, of course. Years ago, less than a mile from my house, a family of four was killed when someone accidentally left their minivan running in the garage. A few years later, we had a large ice storm that took out power for days. A neighbor a few doors down from my house was running a generator in front of their lower level garage door - with the door open. In this case the CO alarm probably saved their lives. Both those types of scenarios continue to cause deaths, alas. It just goes to show that even people with electric heat need CO detectors! And the public needs education on the symptoms of CO exposure as described on my CO web page: http://www.ilpi.com/msds/ref/carbonmonoxide.html My CO detectors have LED readouts that show the level. As described previously, the alarm will show 0 if the [CO] is between 0 and 30 ppm. However, there is a peak level button that you can press that will show the highest level read since the last reset or power up, and that will display levels from 11 to 999 ppm. Of course, the accuracy and precision of the device for low levels is open to question.
