摘要： The present disclosure discloses a calibration vessel for an optical immersion sensor to be calibrated, which is designed for measuring, calibrating and/or adjusting a measured variable. The calibration vessel includes a housing having a repeatably tightly sealable opening for introducing the optical immersion sensor. The housing provides a value for a calibration solution. The opening comprises a guide for aligning and positioning the optical immersion sensor to be calibrated in all possible spatial degrees of freedom, wherein the housing is designed such that the influence of the interactions between the light, emitted and received by the sensor, and the housing wall, in particular as a result of scattering, absorption, reflection, phosphorescence and fluorescence, on the measured value that can be ascertained by the sensor is minimal, wherein the volume of the calibration solution is minimized at the same time.

摘要： A measuring device includes: a measuring cell, which can be manufactured cost-effectively and is easy to handle, insert and/or replace; a measuring cell receptacle for receiving the measuring cell, which is or can be clamped in the measuring cell receptacle; and a sensor for measuring for measuring at least one measured variable for a medium located in the measurement chamber or flowing through the measurement chamber of the measuring cell. The measuring cell includes a measurement chamber through which the medium can flow or which can be filled with a medium and a spring system with which the measuring cell can be clamped in the measuring cell receptacle in at least one clamping direction relating to a measurement chamber axis of the measurement chamber.

摘要： A measuring device for measuring a measurand of a medium includes a measuring cell, a measuring cell receptacle for holding the measuring cell, and a measuring apparatus for measuring the measurand, wherein the measuring cell includes a measurement chamber containing the medium and a reference chamber separate from the measurement chamber and containing a reference medium. The measurement chamber and the reference chamber are arranged relative to one another such that the measuring cell can be inserted into the measuring cell receptacle in a measuring position, in which measurements of the measurand of the medium can be performed by means of the measuring apparatus, and can be inserted into the measuring cell receptacle in a reference position, in which reference measurements of a reference variable of the reference medium in the reference chamber can be performed by means of the measuring apparatus.
