Abstract: A device for calibrating measuring instruments for DLR measurement with optochemical pH sensors. The device includes a calibration head with a calibration layer applied to a carrier layer which contains a non-pH-sensitive dye which has the same optical properties as the pH-sensitive dye used for pH measurement, and the same reference dye as is used for pH measurement. Further including at least one light guide to the first end face of which the carrier layer with applied calibration layer is attached and the second end face of which is used to produce a light-conducting dye, as is used for the pH measurement, and at least one light guide, to the first end face of which the carrier layer with applied calibration layer is attached, and the second end face of which is set up to produce a light-conducting connection to a measuring device for DLR measurement with optochemical pH sensors.
