A measurement cuvette for detecting at least one fluid constituent of a fluid flowing through the measurement cuvette by means of electromagnetic radiation, includes: a channel, which extends through the measurement cuvette along a channel path extending centrally through the channel; a coupling and detection portion, which extends, between its first longitudinal end and its second longitudinal end, along a linear longitudinal axis, detachably mechanically coupled to a radiation component; a physical orientation structure, which allows detachable mechanical coupling of the measurement cuvette to the radiation component in a predefined desired relative orientation and prevents the detachable mechanical coupling in an undesired relative orientation. The physical orientation structure is arranged and formed between the first and the second longitudinal ends of the coupling and detection portion.
