Yes you are right Norbert, it is only for ambient air, Crispin pointed
this out when I first mentioned it and said it would need a dilution
method if it were to be used  to measure flue gas.

I did say milligrams when I meant to say micrograms per cubic metre.

What effect would adding a sampling tube  to it have, I'm thinking it
will restrict the airflow so the count per cubic metre would appear to
be less than otherwise?

I'm interested in seeing how my wood stove affects the air downwind of
my house and as the road outside is  a residential road with peaks of
traffic in the morning and evening I aim to see what changes there are
outside and inside my boundary hedge.
