Each of our standard Viscometers is supplied with an internal spring used to calculate the viscosity of a material. These springs have different measuring capabilities:

  • LV is for low viscosity materials and can measure the thinnest materials. Typical examples include inks, oils, and solvents.
  • RV is for medium viscosity materials than those measured with an LV torque. Typical examples include creams, food, and paints.
  • HA is for higher viscosity materials than those measured with an RV torque. Typical examples include gels, chocolate and epoxies.
  • HB is for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds, and molasses.

Note: Additional special springs are also available upon request.
