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

[Erik Muller <emuller@naic.edu>]

Hello Folks,
I have a quick request for people with a functioning pressure hull (i.e. 
does not need to be a finished sub, just airtight) to see if a simple 
idea for measuring ambient CO2 content is useful. Its a VERY cheap 
system, and should work as a first-order indicator (i.e. not exact, but 
sensitive). Please email me offlist if you are interested and I can 
explain my idea. I might even draw some pictures.
EM.
