A Significant Breakthrough in Viscosity Measurement of Non-Newtonian Fluids
What if you could evaluate the continuous behaviors of paints, creams, greases, polymers and many other kinds of non-Newtonian fluids more quickly, easily and precisely than you ever thought possible? With A&D’s tuning fork vibro method now capable of varying the shear rate, a whole new vista of materials research is wide open ahead of you—.

Vibration Amplitude Made Adjustable to Change the Shear Rate
By simple key operation, the sensor plate amplitude of the RV-10000 can be altered to eight levels (between 0.07 and 1.2 mm peak-to-peak), which create different shear rates. With this function, you can easily measure viscosity changes in response to varying shear rates.

How the Tuning Fork Vibro Rheometer Works

Two thin sensor plates in a tuning fork arrangement are driven with electromagnetic force to vibrate at their natural (resonant) frequency of 30 Hz within the sample fluid. 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 a constant vibration amplitude.

The tuning fork vibro method is recognized as a Japanese industrial standard for viscosity measurement of liquids (JIS Z8803). The viscometer that uses this method is also accredited as a standard device for the Japan Calibration Service System (JCSS) along with capillary and rotational viscometers.

Easy Setup and Very Quick Measurement
Compared with conventional methods, it takes much less time for you to set the sample fluid, start measurement, and obtain the viscosity value (the RV-10000 requires only 20 seconds to stabilize). Moreover, since the sensor plates have a very small thermal capacity, they cause minimal temperature change to the sample fluid upon immersion, realizing fast and stable viscosity measurement

It is also very easy to clean the sensor after measurement – all you need to do is wipe off the sample residue with alcohol.*
*2 In the case of sample fluid sticking to the sensor, an off-the-shelf ultrasonic cleaner will be effective to remove it.

Simultaneous Measurements of Temperature and Viscosity
The temperature sensor (0 to 160 °C range) located between the two viscosity sensor plates allows measurement of viscosity’s dependence on temperature as accurately as possible.

Wide Dynamic Range of Measurements
Relationship Between Vibration Amplitude, Shear Rate and Viscosity Measurement Examples
The RV-10000 has a viscosity detection system that singly measures from very low to high viscosity in quick succession (max. 0.3 to 25,000 mPa.s), which makes the instrument highly versatile and able to cover measurement of various types of fluids by itself. It also allows continuous measurements of viscosity variation over time and/or temperature changes at differing shear rates

.

Extremely High Sensitivity The sensor sensitivity heightened through sharp resonance phenomena even detects viscosities around the level of water with unparalleled precision. Such sensitivity realizes measurements, for example, for finding the cloud point of surfactants and controlling the drinking sensation of beverages.

Excellent Repeatability The RV-10000 achieves repeatability as high as 1% of the measured value (by standard deviation) for the entire measurement range, providing you with consistent results and enabling reliable comparisons of those results
