I was looking into sensor heads briefly at one time, and if I recall the Figaro
device works in some sort of cumulative manner, where you generate a valid
reading every minute or something like that.  I also used and know of others
using a sensor element from Citi-Tek (SP?) in England.  Those units were capable
of generating a continuously updating reading.  I used the CO version and folks
I know are using the other chemical cell versions for other gasses.  The company
has a reputation for good sensor technology.  I just don't know how to read
them.  Any Brittons out there who can link these guys up with Citi-Tek?
