FS FISH SCHURMAN CORPORATION FALLING BALL VISCOMETER 3) GLASS BALLS 3) STAINLESS BALLS 2) STAINLESS WASHERS 1) GLASS STIRRER ROD 1) SMALL FLATHEAD SCREWDRIVER 2) STAINLESS CAPS 1) SMALL SAMPLE HOLDER WITH 2 LIDS SMALL BLACK CASE. THE FALLING BALL VISCOMETER IS USED FOR PRECISE MEASUREMENT OF THE VISCOSITY OF TRANSPARENT "NEWTONIAN" LIQUIDS AND GASES. IT COMPLIES WITH THE REQUIREMENTS SET FORTH IN DIN STANDARD 530 15 AND HAS BEEN APPROVED BY THE GERMAN PHYSICAL TECHNICAL BUREAU FOR OFFICIAL CALIBRATION PURPOSES. MEASUREMENT PRINCIPLE ROLLING SLIDING MOVEMENT OF A BALL IN AN INCLINED CYLINDRICAL TUBE FILLED WITH THE FLUID WHICH IS TO BE EXAMINED. THE TIME IS TAKEN WHICH THE BALL REQUIRES TO TRAVEL A DEFINED MEASUREMENT DISTANCE. THE TEST CYLINDER CAN BE TURNED UPSIDE DOWN FOR ADDITIONAL MEASUREMENT OF THE RETURN OF THE BALL. THE MEASUREMENT RESULTS ARE GIVEN AS DYNAMIC VISCOSITY IN THE INTERNATIONALLY STANDARDIZED ABSOLUTE UNIT OF MEASURE MILLIPASCAL SECONDS [MPA S]. TEMPERATURE CONTROL SINCE VISCOSITY IS HIGHLY DEPENDENT ON TEMPERATURE PROVISION HAS BEEN MADE FOR EXACT CONTROL OF THE SAMPLE TEMPERATURE. THIS CAN BE DONE FOR EXAMPLE WITH THE RECIRCULATION THERMOSTAT OR THE RECIRCULATION COOLER. THE TEMPERATURE IS MONITORED USING A THERMOMETER WHICH HAS BEEN BUILT INTO THE VISCOMETER (STANDARD -1 °C TO 26 °C 0.1 K GRADUATIONS). TYPICAL APPLICATION EXAMPLES THE FALLING BALL VISCOMETER IS USED PRIMARILY FOR LOW-VISCOSITY SUBSTANCES LIQUID HYDROCARBONS (PETROLEUM INDUSTRY) SOLVENTS SOLUTIONS OF PLASTICS AND RESINS AS WELL AS INKS (CHEMICAL INDUSTRY) GLYCERIN RAW MATERIALS (PHARMACEUTICAL INDUSTRY) GELATINS SUGAR SOLUTIONS (FOOD INDUSTRY). .
