A viscometer, or viscosimeter, is an instrument used to measure the viscosity of a fluid.
For liquids with viscosities which vary with flow conditions, a rheometer is used. Viscometers only measure under one flow condition.
A rotational speed is preset and the flow resistance of the sample is measured (torque required) to maintain the set speed, which is proportional to the viscosity.
The viscometer can measure various solutions such as oils, paint, ceramic slurry, pasty creams, PVC plastisols, or mineral slurries. The viscometer provides flow curves, yield points, time curves, and temperature curve results.
