A new combined electrode for submersible probe systems. The pH-combined sensor consists of a reference electrode and a pH sensitive glass electrode in one housing to save one free channel of the probe system.
To realize accurate measurements in the deep sea too, a double diaphragm for the reference electrode was used to avoid problems with the signal stability during pressure
changes. The interface reference electrode/sample is realized in this case by means of a hole diaphragm. Inside the reference electrode follows a KCl containing gel with a special built-in second diaphragm containing the Ag/AgCl-reference system in a potassium chloride solution. The pH-combined sensor for the in-situ determination of pH is available as deep sea version (up to 600 bar) without integrated temperature sensor.
