ABSTRACT:
A cuvette comprising a housing having a passage therethrough and being adapted to receive blood. The housing has a wall with an outer face. An optical window leads from the outer face to the passage and the optical window is transmissive to an optical signal so that a parameter of blood in the passage can be measured. A magnet is carried by the wall and spaced from the optical window for use in providing information about the cuvette. The cuvette is releasably attachable to an optical head. The optical head includes a plurality of Hall effect transducers which respond to the position of the magnet on the housing so that the position of the magnet can be used to provide information about the cuvette.
