    Abstract: The invention relates to an instrument for in situ monitoring a degradation level of refined oil in use. Provided are: an excitation light irradiation part (1) that varies an intensity of excitation light to irradiate the excitation light on refined oil; a fluorescence intensity detection part (2) that detects an intensity of fluorescence that is generated by the irradiation of the excitation light; a time lag characteristic calculation part (33) that calculates a time lag characteristic of a fluorescence intensity variation with respect to the intensity variation of the excitation light; and a degradation index value acquisition part (35) that refers to a correlation between a degradation index value indicating a degradation level of the refined oil and the time lag characteristic to acquire the degradation index value from the time lag characteristic calculated in the time lag characteristic calculation part.
