Abstract:
1. A method for calibrating at least one sensor device of a sensor unit connected to a reaction vessel, wherein the sensor unit comprises at least one sensor device configured to be calibrated, at least one compartment containing a calibrating agent, and a housing, wherein the at least one sensor device and the at least one compartment are accommodated movably relative to one another in the housing which is configured to be connected to the reaction vessel, wherein the sensor unit is arranged so as to calibrate the at least one sensor device by contact with the calibrating agent before chemical and/or physical parameters of a measurement substance are measured with the at least one sensor device, wherein the at least one sensor device is further configured such that the relative movement between the at least one sensor device and the at least one compartment is irreversible, wherein the at least one sensor device is movable relative to the at least one compartment from an initial position in which the at least one sensor device does not contact the measurement substance into a measurement readiness position different from the initial position, in which the at least one sensor device is at least partially contactable by the measurement substance, wherein the method comprises the steps of: inserting a sensitive element of the at least one sensor device into a compartment of the sensor unit containing a calibrating agent, withdrawing the sensitive element from the compartment; inserting the sensitive element into the reaction vessel and locking the sensor device in position, wherein the steps of the method are irreversible.
