<p>Measuring cell for measuring the conductivity of liquids. The measuring cell comprises two opposite outer electrodes, a first current source, a reference electrode and a voltmeter. The measuring cell further comprises a perforated electrode movably placed between the two outer electrodes, a second current source, the first and the second current source applying a first and a second current, respectively, between the outer electrodes and the perforated electrode, displacement means for moving the perforated electrode to various positions, and switching means for switching between the first and second current between the outer electrodes and the perforated electrode. The electrodes, the current sources, the voltmeter and the switching means are situated in a circuit. Method for measuring the conductivity of a liquid while using the measuring cell.</p> |
