viscometer

A viscometer is a device used to measure the viscosity of a fluid—that is, how thick or resistant to flow it is. Think of it as a tool that tells you whether a liquid pours easily like water or more slowly like honey. By analyzing how a fluid moves under specific conditions, the viscometer helps scientists and engineers determine its flow characteristics, which are important in manufacturing, quality control, and research. Different types of viscometers exist for various fluids and applications, but all serve the purpose of quantifying a fluid's resistance to flow.
