Abstract

An electrochemical sensor for fluid media with at least two electrodes, which are in contact with one another via an electrolyte and are accommodated in a housing. Many different sensor variants are attainable with a few, standardized components. The housing (1) includes a plurality of modules (4a, 4b; 4c-4m), which are placed next to one another, are designed as hollow bodies, and are connected to one another, wherein at least two lateral surfaces (9) of each module (4a-4m) are suitable for connection to additional modules (4a-4m), and at least two of the modules (4a, 4b; 4c-4m) accommodate one electrode (2, 3) each, and the hollow space (16) enclosed by the modules (4a, 4b; 4c-4m) is delimited from the environment by the two electrodes (2, 3), on the one hand, and by a partial area (17) each of the inner wall (5) of the modules (4a, 4b; 4c-4m), and is provided for accommodating the electrolyte (18).
