Function and system design

Measuring principle

The measuring cell has four electrodes. An alternating current is applied via the outer electrode pair.

At the same time, the voltage applied is measured at the two inner electrodes. The electrolytic

conductivity between the electrodes can be reliably established based on the measured voltage and

the current flow caused by the liquid's resistance. The advantage of this technology compared to

traditional two-electrode sensors is that electrochemical effects at the live electrodes are suppressed

by the two additional voltage measuring electrodes.
