摘要： 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.

摘要： In the disclosed method, ion activity is measured by placing a cup filled with a test solution to be measured on a cup receiver, lifting a cup lifting arm to engage the cup receiver with a rotary plate, rotating the rotary plate to stir the test solution in the cup, measuring a potential difference between a reference electrode and other electrodes after completion of the stirring of the solution, and indicating the ion activity as a function of the potential differences.
