The point of my original post is not that I have a low level CO detector or
that I make a fermented cabbage relish but that we sometimes have devices to
detect a certain condition but never actually test to verify that they
actually detect that condition. We rely on the device's test circduitry to
tell us it's ok. The CO Experts alarm has an algorithm that measures CO
something like the way the body absorbs the gas. You can interrogate the
unit to see the gas buildup history.
Yesterday morning, I moved the piccallili to the house and reset the alarm.
It still read 13 PPM. This morning the screen was again, as it has been for
two years, blank but I know that the alarm works.
Regards.
