ABSTRACT:
In an apparatus for measuring ion activity, a reference electrode and an at least one test electrode project through an opening in a rotating plate while a cup receiver which holds a cup filled with the test solution is lifted from a disengaged position into a position where the cup receiver engages and is rotated by the rotating plate while the electrodes project into the solution. A measuring circuit connected to the electrodes measures the ion activity with the use of a reverse logarithmic amplifier.
