FUNCTIONAL FLUID STATE DETERMINATION APPARATUS AND FUNCTIONAL FLUID STATE DETERMINATION SYSTEM

摘要

This functional fluid state determination apparatus (100) is provided with: a light source (10) which irradiates, with electromagnetic radiation, a functional fluid (200) that is retained or circulated in a flow channel (310) within machinery (300); a spectrometer (20) which derives a Raman scattering light spectrum by dispersing Raman scattering light scattered from the functional fluid (200); and a determination unit (30) which determines a state of the functional fluid (200) on the basis of the Raman scattering light spectrum derived by the spectrometer (20).
