ABSTRACT:
An arrangement and method is provided for electronically calibrating electrochemical sensors for determining partial pressures in physiological media. In an electrochemical sensor arrangement for sensing such partial pressures, a working electrode with an electropotential which varies relative to time is calibrated by varying the limit oxygen reduction current thereof as a function of the quotient of the potential of a calibration electrode and the measured potential of the working electrode.
