Calibratable sensor unit for reaction vessels
First Claim
1. A calibratable sensor unit for a reaction vessel, comprising:
- at least one sensor device configured to be calibrated; and
at least one compartment containing a calibrating agent;
wherein the at least one sensor device and the at least one compartment are accommodated movably relative to one another in a housing configured to be connected to the reaction vessel;
wherein the calibratable 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; and
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 in which the at least one sensor device is at least partially contactable by the measurement substance, wherein the measurement readiness position is different from the initial position.

Abstract
The present invention relates to a calibratable sensor unit for a reaction vessel, such as for example a fermenter (48), in particular a disposable fermenter, comprising at least one sensor device (14) to be calibrated and at least one compartment (26, 28, 30) containing a calibrating agent, the at least one sensor device and the at least one compartment (26, 28, 30) being accommodated movably relative to one another in a housing (12) that is connected to or can be connected to the reaction vessel (48), wherein the calibrating unit (10) is arranged to calibrate the at least one sensor device (14) 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 (14). According to the invention it is proposed that the sensor device (10) is configured in such a way that the relative movement between the at least one sensor device (14) and the at least one compartment (26, 28, 30) can be carried out irreversibly.
