Sensor module for electrochemically measuring liquid films comprises chambers arranged in a flat container made from a plastic which is resistant over a wide pH region and divided by bars

摘要

Sensor module comprises chambers (1, 2, 3) arranged in a flat container made from a plastic which is resistant over a wide pH region and divided by bars. The chambers contain an indicator electrode formed as silver chloride base bodies, a reference electrolyte in polymer or gel form as a component of an external reference electrode of a potentiometric measuring chain and a chloride-free bridge electrolyte.
