The kinematic viscosity is the measure of the internal friction force when the liquid flows under the action of gravity, and its value is the ratio of the dynamic viscosity to the density at the same temperature, which is one of the important physical and chemical properties of oil grade and quality identification. In practical application, appropriate selection of lubricating oil viscosity can ensure the normal and reliable work of mechanical equipment.
The instrument is the special test equipment designed and manufactured based on the national standard GB265-88 Petroleum Product Kinematic Viscosity Determination, and is suitable for the determination of kinematic viscosity of liquid petroleum products, of the instrument has timer function of sample movement time and automatically calculation function of final results of kinematic viscosity.
