Tuning Fork Vibro ViscometerSV-10/SV-100

Viscometry Revolution!
A&D's original, tuning fork vibro method* promises you high accuracy and a wide measurement range
without replacing the sensor plates!! (* Patent approved)
Tuning Fork Vibro Viscometer SV series measures viscosity by detecting the driving electric current necessary
to resonate the two sensor plates at a constant frequency of 30Hz and amplitude of less than 1mm.

Selectable Wide Measurement Range

Continuous MeasurementSamples with very low viscosity to high viscosity can be measured
without changing the sensor plates, so a wide range ofmeasurements can be made continuously.
(SV-10: 0.3mPa·s-10,000mPa·s / SV-100: 1,000mPa·s-100,000mPa·s)

The SV series allows measurement of the cloud points of samples
such as surface active agents and of surface/interface changes suchas wettability due to its ability to measure a wide range without theneed to replace the sensor plates.

High Measurement Accuracy

Easy Calibration

The SV series, incorporating the innovative tuning fork vibro method,
provides an excellent repeatability of 1% of the measured value(by standard deviation) for viscosity measurement.

Both one-point and two-point calibrations are possible using either
viscosity standard liquids (optional) or samples of known viscosities.
Simplified Calibration function, a one-key operation that utilizes
purified water is also available for the SV-10.

Temperature Measurement

Data Collection and Graphing Software

It is very important to measure the temperature of the fluid correctly
because the viscosity is very much dependent upon the temperatureof the fluid (-2% to -10%/ºC). The SV series can detect accurate
temperature immediately with a temperature sensor (0 to 160 ºCrange) located right next to the viscosity sensor plates.

Highly Stable Measurement
The sensor plates have very small thermal capacity and cause only
minute displacement in the sample liquid, which prevents changes tothe temperature and the physical properties of the sample.

Non-Newtonian Sample
Viscosity Measurement

WinCT-Viscosity (RsVisco) software transmits viscosity and temperature
measurement data to a PC and displays it on a graph in real-time.

Small Sample Size
The standard sample cup requires just over 35ml of sample fluid so there
is very little waste. (Optional 10ml/13ml sample cups are also available.)

Easy Cleaning
Due to their simple structure, the SUS 304 stainless steel sensor
plates and temperature sensor (all gold-plated) and SUS 304 stainlesssteel protector can be quickly and easily cleaned.

Flowing Sample Measurement

Foaming Sample Measurement

Even the viscosity of flowing samples can be measured, including
liquid in turbulent flow, enabling field data measurement, whichis as reliable as measurements in a laboratory.

A low drive frequency of 30Hz allows
measurement of foaming samples
without breaking minute foams and withless influence scattering larger foams.

Sol and Gel Measurement

Vacuum Fluorescent Display

Separated Type Model

Sol and Gel sample fluid like starch can be measured
during the change of material characteristic.

You can avoid unnecessary reading errors with an easy-to-read,large, clear display: 13mm height for viscosity measurement
and 11mm height for temperature measurement.

The SV series is composed of a Display
Unit and a Main Unit offering excellent
placement flexibility.

RS-232C Interface

Accreditation

The RS-232C comes as standard for your PC or
Printer connectivity and the connection cable (25pin – 9 pin) is also standard for your convenience.

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

Thin sensor plates allow little disturbance ofsample texture and thus enable measurement ofstable viscosity values.

Sample Temperature Control
Our water jacket (AX-SV-37) (optional) used in conjunction with acommercially available constant heat water tank to heat the circulating
system, ensures that the sample remains at a constant temperature andthat the temperature can be changed for viscosity measurement.
(A small sample cup AX-SV-34 and a glass sample cup AX-SV-35 are available, as
optional accessories.)

How the Tuning Fork Vibro Viscometer 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 thencalculated based on the proportional relationship between theviscous resistance of the sample fluid and the amount of electric
current required to drive and maintain the sensor plates at aconstant vibration amplitude.
(The value measured by the tuning fork vibro viscometer is the product ofviscosity and density. It is displayed in the [mPa•s] unit of measurement,
assuming that the density of the sample fluid is 1 g/cm3.)

RsVisco software was developed for the transmission of real-time viscosity andtemperature measurement results from the SV series to a PC. The results are
displayed in a graph format with scaling conversion and logarithm display
functions available. The user can save the measurement data as a “CSV” file andopen it using RsVisco for future analysis of a sample.
