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.

A sensor arrangement includes a reaction subassembly having a housing and a detector subassembly. The housing is a layered component arrangement encompassing a luminophore-containing reaction laminate excitable, by irradiation with a first electromagnetic radiation of a first wavelength, to emit a second electromagnetic radiation of a second wavelength different from the first wavelength; and a temperature-detection laminate emitting an infrared radiation. The housing includes an opening for introducing a fluid, a reaction window and a temperature-sensing window. The reaction window transmits the first and second electromagnetic radiation, and the temperature-sensing window is penetrable by infrared radiation. The detector subassembly encompasses a radiation source emitting the first electromagnetic radiation, a radiation detector detecting the second electromagnetic radiation, and an infrared detector detecting, through the temperature detection window, the infrared radiation emitted from the temperature detection laminate. The reaction laminate and the temperature-detection laminate are embodied separately.
