Not rated yet

Are you struggling with an expensive rheometer that only produces unstable results when testing low viscosity (e.g. below 100 mPa•s) samples? Drawing on A&D’s proven sensor technology for high- resolution analytical balances, the RV-10000A Tuning Fork Vibro Rheometer is a breakthrough alternative to conventional methods in the research of non-Newtonian fluid properties, especially for ease and precision in low viscosity measurements.

Two thin sensor plates arranged like a tuning fork, and electromagnetically driven, vibrate at a frequency of 30Hz in the sample liquid.

Viscosity is then calculated based on the proportional relationship between the viscous resistance of the sample fluid and the amount of electric current required to drive and maintain the sensor plates at constant vibration amplitude.

The sensor plate amplitude of the RV-10000/A can be altered between the minimum of 0.07 mm and the maximum of 1.2 mm (peak to peak), while the frequency is kept at 30Hz, which will cause a variation in shear rate.

This allows the user to easily quantify the viscous behaviours of non-Newtonian fluids in response to different shear rates.

A temperature sensor (0 to 160 ° C) located between the sensor panels enables to capture the measuring temperature at the same place during the measurement.

In addition, the sample may be placed in the supplied water jacket with a commercially available temperature control tank, to control the temperature (between 0 and 100 °C) of the sample fluid in order to measure the viscosity at a constant temperature or to see how the viscosity varies with changing temperature.

WinCT – Viscosity (supplied) is software for automatic transfer of the measurement data (temperature and viscosity) to allow further processing. The measurement results can be graphically displayed in real time or can be stored as a “CSV file” for future analysis.
