The housing (14) contains an infrared spectrometer (18) and an optical emission spectrometer (24) for testing a sample (12) of oil. A conduit (32) by operation of a pump (40) draws the sample (12) into the conduit (32), and controllably moves the sample (12) to an infrared spectrometer (18) for testing, and subsequently to an optical emission spectrometer (24) for testing. The pump (40) and spectrometers (18, 24) are controlled by a computer (50) for complete automation of testing. The computer (50) performs analysis and diagnosis of the test results from the spectrometers (18, 24) based on sets of known and standard information.Field of SearchLubricantLubricant LIQUID ANALYSIS OR ANALYSIS OF THE SUSPENSION OF SOLIDS IN A LIQUID Lubricant testing By solid content Content or effect of a constituent of a liquid mixture Metallic particle constituent Liquid constituent of a liquid mixture Plural liquid constituent (e.g., multiphase liquid) By optical irradiation For measuring solid components (e.g., particles) With heating or cooling OIL TESTING (E.G., CONTAMINATION) WITH PLURAL DIVERSE TEST OR ART PLURAL TEST METHODS OF DETERMINING OIL PRESENCE, CONTAMINATION OR CONCENTRATION Using sample absorption for chemical composition analysis | |
