Hi all
I have come by an old barometer - something like the item shown here
http://www.hemswell-antiques.com/ant...ter-33028.html
(although not quite of the quality).
Now I know that these devices measure atmospheric pressure, but I am not
clear on how much this will be affected by the instrument location.
Does a heat source like a radiator change atmospheric pressure?
Can I mount this on a wall above a radiator and expect it to work?
From my memory of the barometer, the needle doesn't appear to move much
in operation. Is this because it was previously in a centrally heated
house, or is there likely to be something wrong here?
Thanks
Phil
Many thanks to all respondents - I'll give it a tap with my pipe and see
what the needle does!
Looks good held up above the hall rad, but I understand the concerns
over the wood.
