Every viscometer / rheometer 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. Examples include inks, oils and solvents (the liquid in which a solute is dissolved to form a solution).
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 (an adhesive, plastic, or other material made from a class of synthetic thermosetting polymers containing epoxide groups).
HB – is for even higher viscosity materials than those measured with an HA torque spring. Typical examples include asphalt, caulking compounds and molasses (thick, dark brown juice obtained from raw sugar during the refining process).
If you are still not sure which of the viscosity instruments will be the best for your project please send us an email with all your questions and details of the project: email@example.com
