Abstract

The present invention relates to the field of measuring and to electrochemical measurement, and more particularly to a reference electrode and to an arrangement for an electrochemical measurement. A reference electrode (13) for an electrochemical measurement according to the present invention comprises an inner reference element (14), which inner reference element (14) has been embedded into a solid electrochemically active composite material (15). An arrangement (16) for an electrochemical measurement comprises an inner reference element (17) and at least one indicator electrode (19), (20), which inner reference element (17) and the at least one indicator electrode (19), (20) have been embedded into a solid electrochemically active composite material (18). The solution according to the present invention may be utilized in any kind of electrochemical measurement in the fields of e.g. clinical analysis, environmental analysis and industrial analysis.
