Abstract
A device for performing electrochemical and/or optical measurements in fluids, includes a sensor part of substantially planar configuration carrying a plurality of sensors that are connected to conductive paths; a cover part, which includes a groove-shaped measuring channel through which the fluid will flow; and a sealing element positioned between the sensor part and the cover part for sealing the measuring channel. The cover part includes grooves which extend in parallel with the measuring channel and which define respective ridges between the grooves and the measuring channel, and the sealing element substantially includes guiding bodies which are retained in the grooves of the cover part and are provided with integrally molded narrow sealing lips protruding in the area of the ridge. The sensor part and the cover part are joined by a plurality of locking elements which are distributed along the measuring channel.
