Best CO (Carbon Monoxide) detector?

[Nick1911]

Right then!  Now that the obligatory thread drift is out of the way, I'll answer the OP's question!

I have one of each of these:

Kidde KN-COPP-B Front Load Battery-Operated Carbon Monoxide Alarm with Digital Display

Kidde KN-COB-B Basic Carbon Monoxide Alarm with Electrochemical Sensor

I really like the digital readout of the first one.  Gives you some data, even before the alarm sounds.

The highest reading I've ever seen was 23 ppm.  This was caused by me accidentally leaving a burner on the gas stove on overnight on 'simmer'.  That level wasn't sufficient to trigger the alarm, though it was nice to see that it picked it up.

Regarding the kids' ability to sleep through an alarm, check out linked alarms where, when one goes off, they all go off.  I don't know if any CO detectors offer linking, but the linked smoke detectors are pretty much the only thing my firefighter friend will consider.

In my Rott's case it was more "bull in china closet".

Now wait.  Mythbusters tested the "Bull in a China Shop" myth and the bulls were actually pretty good and not knocking over everything. 
:D :D

I like that display.  Much better than the one I have.  I just ordered the plug-in version.

We've got one with a digital display and battery backup.  (can't recall the brand at the moment and it's about 5- 6 years old so they probably don't make it anymore). 


It does wail like a dying banshee when we lose power. 

Only had it go off once (new gas stove installed and the oven burner wasn't properly adjusted).  Once or twice I've seen it read "001" and then watched as it went back to "000".
