Tom, or anyone,
Have any of you seen an instrument such as this: http://www.oxyguard.dk/439 ? It is supposed to be able to measure dissolved CO2 in water, with a probe that is sensitive only to dissolved gaseous CO2, not carbonic acid or HCO3 ions. I suspect it costs over $1000, but wouldn't this be nice to have?
