Clark electrode – Oxygen sensor

The oxygen sensor measures the dissolved oxygen in the water using polarographic methods. The platinum cathode has a diameter of 4mm and is encased with a teflon membrane. The oxygen current consumption ranges from 0 to 12 μA due to the big diameter of the platinum wire. The relative high current consumption requires a minimum current flow of 10 cm/sec in order to avoid qxygen depletion in front of the membrane.
The sensor has a limited lifetime of typical 12 – 16 month. Since the membrane and electrolyte cannot be exchanged, it has to be replaced.
