Abstract
An electro-analytical measuring process and apparatus for the determination of the concentration and the ion-activity of stationary or flowing solutions or of the partial pressure of gases. The measuring cell of the measuring equipment--connected to an electronic signal processor--comprises, in addition to one or several sensing elements and reference electrodes, at least one fluid clutch capable of galvanically short-circuiting one or more parts of the measuring chain. The measuring cell of the measuring equipment comprises, in a given case, integral sensing unit and standardizing media, being in contact with sensing elements. Further, a control unit for programming short-circuiting belongs to the measuring cell, a fault compensating unit producing signals is connected to the control unit--for calculating the value of the parameter to be measured--is connected to the output of the fault compensating unit.
