Re: [PSUBS-MAILIST] test of CO2 safety hardware - any volunteers?

[Warren Greenway <opensourcesub@yahoo.com>]

My only problem with the CO2 sensors I have used is 
that they aren't very accurate above atmospheric
levels of CO2 and they take hours to restabilize if 
they saturate. I have found some that don't have these
problems, but they are in the $400 range. If you know
of a cheaper one that is reliable, I would love to
get some info on it.
