This tester is designed and manufactured specially according to the national standard “ GB265 – 88 Determination of kinematic viscosity of petroleum products “ . It’s suitable to determine kinematic viscosity of liquid petroleum products. This apparatus has the function of timing of the trial sample movement and can calculate the final result of kinematic viscosity. This method is suitable to determine kinematic viscosity of liquid petroleum products ( It refers to Newtonian liquids ), and its unit is m2/s. Generally in actual utilization, the unit is mm2/s. The dynamic viscosity is equal with the result which use kinematic viscosity to multiply the density of the liquid.  By this method, , it can determine the time that the liquid with the certain volume flows past the calibrated glass capillary viscometer under the gravity in the certain stable temperature and the value that the constant value of capillary in the viscometer multiplies the flowing time, that is , the determined kinematic viscosity of liquid at the temperature. At the temperature, the value that kinematic viscosity multiplies the density of the liquid in the same temperature is the dynamic viscosity at the temperature.
