A viscometer is an instrument used in chemistry to determine how thick or thin a liquid is. This property is called viscosity. Try to pour syrup and water. The syrup is a thick, slow flowing liquid while the water is thin and flows fast. Scientists and engineers need to understand these differences in viscosity for all kinds of reasons, including creating products or testing materials and even understanding the behavior of liquids found in nature. Companies like ZONWON makes automatic viscometer that allows people in the lab and in industry to better understand liquids. It is useful to know the viscosity of a liquid in many things we do, from mixing paint to food preparation. What is the best possible recipe or design for a new product?
