A U tube viscometer is a unique instrument that allows you to determine if a liquid is thick or thin. Knowing how viscous a liquid is can be critical in many industries, whether they are dealing with food or cosmetics, oil and gas. When we discuss viscosity, what we are really discussing is how readily a liquid can flow. A denser liquid (say, honey) moves more sluggishly. A thinner liquid, such as water, travels fast. ZONWON makes the best quality Viscometers U tubes that are easy to work with and highly precise. This tool is important to scientists and engineers who need a way to measure the viscosity of their materials in order to make sure they will work as intended.
