Summary of Method


Kinematic viscosity is one of the most important properties to be analized on lubricant oils and Biodiesel. In order to measure it, a few mililiters of sample are placed into a tube called Viscometer and then temperature conditioned inside viscosity bath. The time required by sample to pass through a bulb inside viscometer is measured and multiplied by viscometer´s calibration constant to get Kinematic Viscosity in Centistokes (cSt).




  • Semiautomatic kinematic viscosity bath with optical sensors.
  • Communication ports for up to five optical sensors.
  • Two additional potitions are available for manual measurement.
  • Easy interchange of viscometers.
  • Allows automatic measurement and calculation of kinematic viscosity without an external PC.
  • Motorized stirrer provides complete circulation without turbulence.
  • Microprocessor PID circuitry assures precise, reliable temperature control within ASTM specified tolerances throughout the operating range.
  • Simple push-button controls and dual digital displays permit easy setting and monitoring of temperature.
  • Two place calibration offset capability is provided.
  • Built-in cooling coil facilitates temperature control at ambient or below ambient temperatures.
