Industrial (Process) pH Electrodes
They are steam sterilisable and used in process industries in biotechnology industries.
Process applications present some major challenges to the pH measurement system. The most common are long distances, temperature extremes, electrical interferences, high pressure, junction poisoning or fouling and chemical/physical breakage. For each of these common problems, developed specific electrodes for excellent performance in all types of process applications.

Due to the high resistance of the glass membrane inside a pH electrode, conventional pH measuring systems utilize high impedance signal transmission. Poor insulation of the electrode connectors and cables results in high susceptibility to electrical leakage/noise and humidity which tends to give erroneous pH readings. As a result, particular care has to be taken in connecting the electrode to the metering system. For this conventional system, the cable length is restricted to typically less than 33’ (10 m). A high impedance meter is required and it is necessary to provide for high insulation at all connections.
