With the proliferation of digital cameras, why not take a photograph of the oil sample (requires the use of a transparent sample bottle) and store the image in a trending software for comparative purposes. Record a new oil sample and use this as a baseline. Set the bottle against a white background such as a sheet of paper to maintain a consistent color comparison. You can also use the camera in other ways such as to record images of the machine and sampling point as a means of identifying it in the software or to record abnormalities.
