Viscometer
Ease of use, flexibility, reliable performance and quality of service have made Brookfield Laboratory Viscometers favorites all over the world.
Each of our standard Laboratory Viscometers/ Rheometers are 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
