This is a viscometer tube, a special apparatus that measures how thick or thin a liquid is. This thickness is called viscosity. Syrup, when you do think of it is thick and slow moving. It’s a thin liquid, and it flows fast. Viscometer tubes are used by scientists and engineers to understand how liquids flow in a variety of industries. For instance, they are key in producing food, paint and even oil. Here at ZONWON, we make some of the best viscometer tubes to make sure that readings will be as precise as possible. This is significant because understanding how a liquid flows can influence the way we fabricate things.
