Re: Questions on CO monitoring

["elk" <elk@wananchi.com>]

I've not yet managed to access the $75 CO meter site that Tami has found-
problems with internet connectivity at the moment- but I can comment on a
couple issues.

10 minutes in a closed-room (known volume) situation would be fine for me.
We work with what we have, and at this point ANY reliable CO measurements
would very welcome.

Obviously we would all like to saunter past a cookstove or fire and simple
wave a probe over it to record the precise CO emissions- but I rather doubt
that even the most expensive equipment will give a proper reading that way.

Which of course leads to further questions....... assuming an unlimited
budget, what would be the best portable equipment you could get for
out-of-the-lab work like this? I bet there isn't a simple answer here. We do
need a know-volume of some sort, don't we? If that's the case, then we CAN'T
be in a hurry, and a 10-minute sample time would be fine.
