A rheometer is a device that measures the flow properties of a non-Newtonian fluid.
Measurements can be made under a wide range of conditions to evaluate the rheological properties of non-Newtonian fluids. It is used in various fields such as medicine, food, cosmetics, and chemistry.
We offer A&D's RV-10000A tuning-fork vibration rheometer as a rental machine.
The new measuring method "tuning-fork vibration type" enables highly accurate continuous measurement from low viscosity 0.3 mPa・ s to 5,000 mPa ・s.

*1. When using a sample container (45mL)
*2. Repeated measurements with the oscillator in the liquid.
*3. the value under temperature range is 20 to 30℃, in a non-condensing environment, and after calibration with the standard liquid for viscometer calibration. If measurement is performed over a long period of time, perform calibration using standard liquid or pure water periodically as necessary.
