Kinematic Viscosity Meter

The Petroleum Product Kinematic Viscosity Tester is a specialized testing instrument designed and manufactured in accordance with the national standard GB265-88 “Method for Determining Kinematic Viscosity of Petroleum Products.” It is suitable for measuring the kinematic viscosity of liquid petroleum products.

This instrument measures the time taken for the sample to flow and automatically calculates the final kinematic viscosity result. This method is applicable for determining the kinematic viscosity of liquid petroleum products (Newtonian liquids), expressed in m²/s, though commonly used in practice as mm²/s.

Dynamic viscosity can be obtained by multiplying the measured kinematic viscosity by the liquid's density. This method determines the time taken for a fixed volume of liquid to flow under gravity through a calibrated glass capillary viscometer (Parshall or Ubbelohde) at a constant temperature. The product of the viscometer's capillary constant and the flow time represents the kinematic viscosity of the liquid at that temperature. The product of the kinematic viscosity at that temperature and the liquid's density at the same temperature yields the dynamic viscosity at that temperature.
