1. A device for measuring and displaying the glucose concentration in the blood by means of disposable sensors comprising a biomembrane and a display device which works on the basis of the glucose concentration diagram and evaluates the measurement results of the sensors, the display device having a calibration means wherein:

  • A) the display device comprises a computer with a time measuring device, whose zero setting is correlated with the date of manufacture of the disposable sensors in an irreversibleB) an irreversible calibration of the glucose concentration diagram is provided which corresponds to the characteristics of the biomembrane of the disposable sensors at the time of their manufacture;

    C) at least one automatic and irreversible correction of the glucose concentration diagram which is influenced by the time measuring device is provided which takes into account the time-dependent characteristics of the biomembrane of the disposable sensors.
