Viscometry Revolution!

Newly developed Tuning-fork Vibration method* promises you high accuracy and a wide measurement

range without replacing the sensor plates!! (* Patent approved)

Sine-wave 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.

Non-Newtonian Sample

Viscosity Measurement

Thin sensor plates allow little disturbance of

sample texture and thus enable measurement of

stable viscosity values.

Flowing Sample Measurement

Even the viscosity of flowing samples can be measured, including

liquid in turbulent flow, enabling field data measurement, which

is as reliable as measurements in a laboratory.

Foaming Sample Measurement

A low drive frequency of 30Hz allows

measurement of foaming samples

without breaking minute foams and with

less influence scattering larger foams.

Sol and Gel Measurement

Sol and Gel sample fluid like starch can be measured

during the change of material characteristic.

Standard RS-232C Interface

The RS-232C comes as standard for your PC or

Printer connectivity and the connection cable (25

pin – 9 pin) is also standard for your convenience.

Vacuum Fluorescent Display

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.

JCSS (Japan Calibration Service System)

The SV series measurement method has been recognized in Japan by JCSS as an official viscosity

measurement instrument, which meets JIS Q 17025 (2005) requirements (equivalent to ISO/IEC17025: 2005).

The SV series measurement method also complies with the Guide to the expression of uncertainty in

measurement (GUM) and ISO/TR 3666 (1998) – Viscosity of water.

Separated Type Model

The SV-10 series is composed of a

Display Unit and a Main Unit offering

excellent placement flexibility.

Our water jacket (AX-SV-37) (optional) used in conjunction with a

commercially available constant heat water tank to heat the circulating

system, ensures that the sample remains at a constant temperature and

that 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.)

AX-SV-37 Application of temperature control of sample fluid

Water jacket (body: polycarbonate, packing: silicon gum)

• Small sample cup & lid (4 of each provided)

• Can be used with the small sample cup provided, or with a glass sample cup (AX-SV-35)

• Specifications Application temperature range : 0°C –100°C

Outer dimension of nozzle for circulation : 10.5mm diameter

•

A stirrer can be set at the base of the water jacket, and can stir up to a viscosity of 1,000mPa·s. (SV-10 only)

Stirrer: VARIOMAG MICRO made by H+P Labortechnik (Germany)

Please use a rotator with dimensions 6mm (length) x 4mm (diameter).

Selectable Wide Measurement Range

Samples with very low viscosity to very high viscosity can be

measured without changing the sensor plates, so a wide range of

measurements can be made continuously.

(SV-10: 0.3mPa·s-10,000mPa·s / SV-100: 1,000mPa·s-100,000mPa·s)

High Measurement Accuracy

The sine-wave Vibro Viscometer SV series, incorporating the

innovative Tuning-fork Vibration Method, provides an excellent

repeatability of 1% of reading for viscosity measurement.

Temperature Measurement

It is very important to measure the temperature of the fluid correctly

because the viscosity is very much dependent upon the temperature

of the fluid. The SV series can detect accurate temperature

immediately because the fluid sample and the detection unit (sensor

plates) with small surface area/thermal capacity reach thermal

equilibrium in only a few seconds.

Real-time Measurement

The SV series sensor plate is very thin and small, both in area and in

mass, which means that the sample is not adversely affected by

temperature change. As a result, a stable viscosity measurement can

be monitored in real-time.

Continuous Measurement

The SV series Tuning-fork Vibration Method does not disturb the

sample fluid and allows measurement of cloud point of samples such

as surface active agents and of surface/interface changes such as

wettability due to its ability to measure a wide range without the

need to replace the sensor plates.

Viscosity Calibration

Using a Viscosity Standard, viscosity calibration can be easily done. 1 point

calibration or 2 point calibration is selectable in the calibration mode.

Data Collection and Graphing Software

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 stainless

steel protector can be quickly and easily cleaned.
