ABSTRACT:
An electrochemical cell for measuring the activity of one or more ionic species such as pNa, pK, pCa, pNH.sub.4, pCl etc. consisting of two sensors selective to the actual ionic species, one of which is used as the reference electrode and the other as the measurement electrode.
The two sensors are chosen preferably identical.
The electrode used as the reference electrode is brought into contact with a solution of known ionic activity and an ionic strength which is greater, equal to or substantially greater than that of the unknown solution to be measured.
The measurement electrode is brought into contact with the unknown solution to be measured, while a third electrode is used purely for instrumental reasons and does not participate in the measurement.
