A U-tube viscometer is a unique instrument that determines how thin or thick a liquid is. It is useful for scientists and engineers trying to grasp the motion of various fluids, whether oil, water or syrup. The more viscous the liquid, the more difficult it is to flow. This device helps us understand how resistant a liquid is to flowing. At ZONWON, we specialized in manufacturing the best equipment – including U-tube Viscometers that have helped industries take quality readings on their fluid.
