Kinematic Viscosity Tester-Petroleum Products Test Equipment

The Petroleum Products Kinematic Viscosity Tester is a specialized instrument used to measure the kinematic viscosity of liquid petroleum products (Newtonian fluids). You determine viscosity by allowing the liquid to flow through calibrated glass capillaries at a constant temperature, measuring the flow time, and applying the capillary constant to calculate kinematic viscosity. You can also derive dynamic viscosity by combining with the liquid density. This tester is widely applied in petroleum, petrochemical, oilfield, transportation, research, and metrology sectors for quality control and scientific studies.
