Principle of Measurement
The Visco-Corder uses reaction torque for dynamic measurement. Reaction torque is developed by submersing a sensor element in a rotating sample vessel containing the test material and measuring the resultant torque expended by the material on the sensing device. The torque is measured in units of either Centimeter-grams (cm-g) or Brabender Units (BU). The measured torque, time and speed data can then be utilized to calculate the apparent viscosity and characterize the flow behavior of the test material.
The New Visco-Corder Model VC-E utilizes high precision torque cell technology to measure the viscosity of Newtonian and non-Newtonian materials.
In the Chemical Industry the instrument is used to evaluate a wide range of materials for the laboratory, production and quality control. Its application can be used to measure apparent viscosity and perceived difference in the flow properties of fluids, pastes, slurries and semi-solids with particulates. It may be used to characterize the flow behavior of materials and to predict consistency, processing ability or stability. The Visco-Corder® offers a wide measurement range, from a few centipoises up to 700,000 centipoises. The unit offers a menu driven electronic keypad and display for ease of operation and observation of data.
The robust, rugged design is well suited for the toughest production and/or laboratory environment.
