Thanks to you and Jerry for that.
I guess it would be simpler to make a ph meter take readings and feed these
into a computer and therefore record and display the derived CO2 value.
You could even put the value on the Web or on your mobile phone then. ;-)
I'll see if I can find out more on the hardware used in ph meters.
Though I'd be very surprised if there isn't a ph meter that can do this already?
