Abstract

The invention concerns a sensor cassette that can be inserted into an analyzer comprising a continuous measuring channel for receiving fluidic media and sensory elements for determining chemical and/or physical parameters of the fluidic media. According to the invention the sensor cassette consists of at least two permanently connected but separately manufactured modules which each have a housing and a measuring channel section wherein the measuring channel sections of adjacent modules are connected to the continuous measuring channel by a fluidic coupling and wherein at least one of the connected modules is designed as a sensor module and has a sensor array comprising at least two sensory elements. Furthermore, a memory element is allocated to the sensor cassette on which specific information for the sensor cassette in particular with regard to its construction from the respective modules is stored.
