Description
The sensor features a field replaceable, gel-filled pH electrode. The electrode’s reference is protected by a special porous PTFE ring which is impregnated with a special conductive gel. The protection ring prevents chemical or biological fouling from reaching the reference, extending the life of the combination electrode. At the end of its life, the electrode can be replaced by the user in the field without the need to return the sensor to the factory.
