Abstract: A sensor cassette insertable into an analysis module for carrying out electrochemical measurement processes in sample fluids, including a sensor carrier which is essentially planar and carries electrochemical sensor elements for determining chemical and/or physical parameters of the sample fluids. The sensor elements are connected to conductor tracks formed on the sensor carrier. A cover part is arranged on the sensor carrier, in which at least one groove-shaped measuring channel that is intended for the flow of the sample fluid and opens towards the sensor carrier is formed, which measuring channel is connected to at least one electrochemical sensor element and is fluidly connected to at least one fluid connector arranged on the side facing away from the sensor carrier. The cover part is a two-component injection molded part having a hard component and a soft, component. The measuring channel is formed in the soft component over its entire length.
