A VISUAL PROCESSOR ANALYSER; AN OPTICAL DEVICE FOR VIEWING SOLIDS AND BUBBLES IN CLEAR LIQUIDS. THE ANALYSER IS ENCASED IN A STAINLESS STEEL CASING. WITHIN THIS CASING IS A CINEPHOTOMICROGRAPHIC UNIT WITH MICROSCOPE THAT IS FOCUSED ON LIQUID PASSING THROUGH AN INCORPORATED HIGH PRESSURE FLOW CELL. FROM THE SYSTEM THE UNIT FREEZES THE PICTURE APPROXIMATELY 20 TIMES PER SECOND AND DETERMINES THE SIZE, SHAPE AND NUMBER OF ANY PARTICLES PRESENT. THE ASSOCIATED COMPUTER (NOT THE SUBJECT OF THIS CLASSIFICATION) HAS THE CONTROL AND MEASUREMENT SOFTWARE DOWNLOADED. THE INFORMATION OBTAINED IS USED TO QUANTIFY AND DIFFERENTIATE ANY MATERIALS IN THE LIQUID. THE SYSTEM MAY INCORPORATE FLOW CONTROL VALVES TO REGULATE THE LIQUID FLOW. A PURGE UNIT MAY ALSO BE INCORPORATED FOR USE IN HAZARDOUS AREAS.

CLASSIFICATION IS DETERMINED ACCORDING TO GIRS 1 AND 6. CN 90112090 FOR OTHER MICROSCOPES, FOR PHOTOMICROGRAPHY, CINEPHOTOMICROPGRAPHY OR MICROPROJECTION: OTHER. NOTE 3 TO CHAPTER 90 HS EXPLANATORY NOTE (A) TO HEADING 90.11
