Automatic Kinematic Viscometer

Viscosity is defined as the rate of a fluid’s internal resistance to flow. Intermolecular force, molecular mass and temperature are considered as the main factors effecting the viscosity. Fluids that have directly proportional flow rate with friction resistance are called as Newtonian fluids. Viscosity values of Newtonian fluids are commonly determined in terms of kinematic viscosity. Best method to measure kinematic viscosity of Newtonian fluids is by using capillary (kinematic) viscometers. For the kinematic viscosity measurements of Newtonian fluids, automatic kinematic viscometer instruments provide the most reliable results by precise temperature and timing control.

Automatic kinematic viscometer provides the most reliable results by precise temperature and timing control. All operations as kinematic viscosity measurement, viscometer cleaning, calibration etc. are handled automatically. This leads to eliminate bias between different operators while providing reliable results.
