PROBLEM TO BE SOLVED: To eliminate a labor to pick up and to measure the lubricating oil every time from a lubricating oil using apparatus, and to manage the timing and the like to exchange or to add a new lubricating oil adequately, in a lubricating oil managing system. SOLUTION: The lubricating oil being used in a lubricating oil using apparatus 8 is led to a cell 2 for measuring passing through a lubricating oil line 3, and after the infrared ray is radiated there, and the infrared ray permeating the lubricating oil is measured by an infrared spectrophotometer 1, the lubricating oil returns to the lubricating oil using apparatus 8 passing through the lubrication oil line 3. At the infrared spectrophotometer 1, the measuring data are detected at every wavelength, and the infrared spectrum data is output to a computer controller 4. The computer controller 4 drives the oil deterioration preventive devices of an addition agent input device 5, a moisture removing device 6, and a lubricating oil exchange device 7, depending on the infrared spectrum data. |
