Introduction:

The Hanna HI 4105 Carbon Dioxide  gas sensing electrode
is a combination electrode designed for the measurement
of Carbon Dioxide in aqueous solutions such as water, soft
drinks or wine, samples.  Carbonate and Bicarbonate ions
are also measured by conversion to Carbon Dioxide gas
upon ISA addition.
