1012827 Includes Only:Falling sphere viscometer with 6 spheres and 1 ball gaugeThermometer 0 - 100° CCleaning setTest certificate with accurate values for sphere constant K and density Po for converting duration of fall to actual viscosity.Falling Sphere Viscometer. Hoppler-type falling sphere viscometer for simple but accurate measurement of dynamic viscosity of transparent Newtonian fluids. The sphere rolls and slides inside an inclined cylindrical tube filLed with the fluid to be tested. The viscosity is measured in mPa s and is derived directly from the time the sphere takes to fall a specified distance through the fluid in the measuring tube. The tube can then be turned upside-down so that time the sphere takes to fall back can also be measured. The tube is situated inside a water bath, which can be filLed with water at a specific temperature in order to measure how viscosity depends on temperature.Features:Light oils, machine oils, petroleum, petroleum ether, diesel (mineral oils and fuels)Plastic solutions, resin solutions, adhesive solutions, latex dispersions (polymer chemicals)Printers' ink, varnish, water-based paints, inks (inks and paints)Emulsions, suspensions, solutions, extracts (cosmetics/pharmaceuticals)Emulsions, dispersions (paper industry)Liquid detergents, washing-up liquid, surfactant solutions (detergents)Honey, fruit juice, beer, milk (food industry)Gases and mixtures of gasesMeasuring range: 0.5 mPa s to 7x104 mPa s (as per DIN 53015)>7x104 mPa s (for sphere fall times > 300 s)Spheres: #1, #2: Borosilicate glass #3, #4: Ni-iron #5, #6: STeelDiameter of spheres: 11.00 to 15.81 mmDiameter of measuring tube: 15.95 mmFall times for spheres: 30 to 450 sOperating angle: 10° to vertical.
