METHOD AND DEVICE FOR THE ANALYSIS OF OILS AND TECHNICAL SERVICE FLUIDS AND FOR THE QUALIFIED EVALUATION OF THE OPERATING STATES OF UNITS

摘要

A method and device for analyzing oils, technical service fluids and for the evaluation of the operating states of units, wherein a drop of test fluid to be examined is applied to a test medium which is allowed to penetrate the medium, and is evaluated after a preselected time by optically comparing a resulting image with the data of a plurality of reference images with respect to a plurality of test criteria. The test fluids to be examined can give information about the state of the test fluids. Fast and reliable detection, evaluation, and assessment are possible and reduce the influence of subjective assessment influences. A computer-assisted comparison of the data of the images with the data of the reference images is performed. Data of the images from the front, back-light, and possibly the UV back-light recording are associated with images for a test criterion that has the greatest correspondence.
