The present invention makes possible to correct the output of (prepare a calibration curve for) a photodetector 4 used for a spectroscopic analyzer 100 or a spectroscope, in a short period of time with a simple configuration. The present invention is adapted to make light beams emitted from a light source 1 enter the photodetector 4 both when interposing an optical element 6 having known characteristics and when not interposing the optical element 6, and acquire a first output value and a second output value that are the output values of the photodetector 4 with respect to each of light beams that respectively have predetermined multiple wavenumbers and are included in the incident light beams ,and obtain an arithmetic expression for calculating intensity of incident light beams from an output value of the photodetector, using parameters that are a ratio between the first output value and the second output value at each of the predetermined wavenumbers and the wavenumber transmission or reflection characteristic of the optical element.

A purpose of this invention is to provide an electrode that is extremely preferably used for measuring a pH of a cell culture medium. This electrode is designed to be inserted into an insertion bore arranged on a container into which a sample solution as being a measuring object is put, and comprises an internal electrode, a storage that houses the internal electrode, a gelled or liquefied internal liquid that is filled into the storage so as to contact the internal electrode, and a sensor part that is electrically connected to the internal electrode through the internal liquid and arranged at a distal end surface of the storage as to detect a electric potential of the sample solution. The storage has a positioning surface for positioning the storage at a mounting position at which the inner wall surface of the container and the distal end surface of the storage are on the same plane.
