Dear Crispin,
I had in mind the testing of the quality of indoor air. Sorry that I was not
sufficiently explicit about this point. I think that one measures the CO
because one would like to avoid deaths by CO poisoning.  If it is just the
stove performance that one is interested in,  values of O2 in and O2 out,
together with parameters like total fuel burned and quantity of water
boiled, might be enough.
Yours
A.D.Karve
