So CB., Co detectors that are UL approved and independantly tested
accurate, or better yet working, by many groups, one nationaly known,
who even compares them, Consumer Reports are wrong. No I don`t believe
it. There are deaths of course but 100x more people are made sick.
Funny how nobody in the media has made this a public issue yet. for if
they were as bad as you believe it would be headline news. Probably
the most independantly tested device made is your hardware store Co
detector. For true accuracy , yes I believe you, as few even simple
thermometers and no cheap analog hygrometers have I ever ever seen as
100 correct. But to do their job and register, record, levels that are
higher than Zero , I see them as working to inform of possible danger,
there fore they work. I would not expect a pro to walk into my house
with a first alert home wall unit, yes Id laugh and throw him out. They
just are not designed for the abuse of what a pro puts them through.
