เครื่องวัดความหนืด DV3T

Rheometer

A 7-inch full color touch screen conveniently displays all test parameters along with measured values for yield stress, viscosity and temperature. On screen graphing shows real-time test data which can be captured in stand-alone mode, recorded on a printer or sent to a PC. Built-in math models, such as Power Law, can provide rapid data analysis for flow index and other selectable variables. Quick, straight-forward, single point viscosity is also easily accomplished with the DV3T making it the ideal "all-in-one" instrument for busy QC labs as well as demanding R&D departments doing comprehensive flow behavior.

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, and molasses.

Additional special springs are also available upon request. To learn more about spring ranges and model selection, please call Brookfield Engineering or one of our authorized dealers.
