This instrument is designed and manufactured in accordance with the national standard "GB265-88 Petroleum Products—Determination of Kinematic Viscosity" as a specialized testing device, suitable for determining the kinematic viscosity of liquid petroleum products. The instrument features timing of the sample's flow time and automatic calculation of the final kinematic viscosity result. This method is applicable for determining the kinematic viscosity of liquid petroleum products (referring to Newtonian liquids), with units of m2/s, though mm2/s is commonly used in practice. Dynamic viscosity can be obtained by multiplying the measured kinematic viscosity by the density of the liquid. This method involves measuring the time for a fixed volume of liquid to flow under gravity through a calibrated glass capillary viscometer at a constant temperature. The product of the viscometer's capillary constant and the flow time gives the kinematic viscosity of the liquid at that temperature. The product of the kinematic viscosity at that temperature and the density of the liquid at the same temperature yields the dynamic viscosity at that temperature.
