The product of the capillary constant of the viscometer and the flow time is the kinematic viscosity of the liquid measured at the temperature (the product of kinematic viscosity at the temperature and the density of the liquid at the same temperature is the dynamic viscosity of the liquid at the temperature).Īutomatic viscosity measuring instrument for petroleum products, using advanced fuzzy PID temperature control technology, accurate temperature control, accuracy up to ☐.02℃. Automatic kinematic viscosity tester for petroleum products, in line with GB/T265-1988 "kinematic viscosity measurement of petroleum products and dynamic viscosity calculation method", suitable for the determination of kinematic viscosity of liquid petroleum products (Newton liquid), the method refers to a constant temperature, Measure the time when a certain volume of liquid flows through a calibrated glass capillary viscometer under gravity.
