Viscosity Measurement

Viscosity is defined as the rate of a fluid’s internal resistance to flow. Intermolecular force, molecular mass, and temperature are considered to be the main factors affecting viscosity. Fluids that show a directly proportional relationship between flow rate and friction resistance are classified as Newtonian fluids. The best method to measure the viscosity of Newtonian fluids is by using capillary viscometers. Through these apparatuses, we can derive kinematic viscosity from the flow time of a fluid kept at a constant temperature within a capillary with known diameters and lengths.

Automatic Kinematic Viscometers

• • Automate sampling, measurement, and wash process to increase operator efficiency.
  • Shorten analysis cycles.
  • Lower your solvent consumption with fully automatic washing and drying operations.
  • Automatic calibration options minimize time and the amount of reference materials used.
  • Wide-range viscometer tubes eliminate the requirement for tube replacements.
  • Minimize deviations due to operator error.
  • Apply measurements within a wide temperature range with built-in heating and cooling components.
  • Analysis data can be stored on the device database or transferred to USB or a PC.
