Falling Sphere Viscometer
Höppler-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 timethe 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.
Includes:
Falling sphere viscometer with 6 spheres and 1 ball gauge
Thermometer 0 – 100° C
Cleaning set
Test certificate with accurate values for sphere constant K and density for converting duration of fall to actual viscosity.
