FAQ
- What is a digital rotational viscometer?
A digital rotational viscometer is an instrument that measures the viscosity of liquids using a rotational principle. It digitally displays viscosity values and ensures stable, accurate results for laboratory or industrial testing.
- What is the working principle of a rotational viscometer?
It rotates a spindle at a controlled speed in the sample. The resistance of the fluid to this rotation is converted into viscosity. The measured torque determines the viscosity value.
