Measurement Principle for SV-Series
The SV series has 2 thin sensor plates that are driven with electromagnetic force at the same frequency by vibrating at constant sine-wave vibration in reverse phase like a tuning fork.

The electromagnetic drive controls the vibration of the sensor plates to keep in constant amplitude. The driving electric current, which is exciting force, will be detected as the magnitude of viscidity produced between the sensor plates and the sample fluid. The coefficient of viscosity is obtained by the correlation between the driving electric current and the magnitude of viscidity.

Sample Temperature Control
A water jacket is provided as standard to be used in conjunction with a commercially available constant heat water tank to heat the circulation system. This ensures that the sample remains at a constant temperature and that the temperature can be changed for viscosity measurement (0 to 100°C).
 
Standard Windows Communication Tools WinCT-Viscosity and a Serial-USB Converter
The graphing program RsVisco receives the viscosity and temperature data from the SV-A series and creates a graph on a personal computer in real time. As such, changes in viscosity and temperature over time as well as the correlation between viscosity and temperature can be observed visually.
 
Tuning-fork Vibration Viscometer
The tuning-fork vibration viscometer has a pair of thin sensor plates of the same natural frequency, which are driven with electromagnetic force to vibrate at the same amplitude. The viscidity produced between the sensor plates and the sample liquid is detected based on the amount of electronic current required to drive the sensor plates and maintain them at a constant amplitude.
  • The vibration viscometer is accredited as a Japan Calibration Service System (JCSS) standard device by the National Institute of Technology and Evaluation (NITE), along with the capillary viscometer and the rotational viscometer.
  • The sensor plates have very small thermal capacity and cause only minute displacement in the sample liquid, which prevents changes to the temperature and the physical properties of the sample.
  • Since the two sensor plates vibrate in reverse phase, it is possible to measure the viscosity of a sample while flowing or being stirred.
 
Portable Sensor Unit
The sensor unit can be detached to perform measurements on location at a manufacturing factory, field research, etc. A portable carrying case is also provided as standard.

Wide-range, Continuous Measurements without Replacing the Sensor Plates
Unlike the rotational viscometer, which requires several different rotors to cover a wide range of measurements, the SV-A series is capable of using the same, fixed sensor plates to perform continuous measurements from very low to high viscosity [SV-1A: 0.3 - 1000mPa•s (cP), SV-10A: 0.3 - 10000mPa•s (cP), SV-100A: 1000 - 100000mPa•s (cP)].
 
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.
 
High Measurement Accuracy
Sine-wave Vibro Viscometer SV series, incorporating innovative Tuning-fork Vibration Method, provides 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. SV series can detect accurate temperature immediately because the fluid sample and the detection unit (sensor plates) with small surface area/thermal capacity reach the thermal equilibrium in only a few seconds.
 
Real Time Measurement
The sensor plate for the SV series is of a thin and small size, in area and in mass, making it less influenced by the temperature change of the sample fluid and as a result the viscosity measurement tracks the change of viscosity of sample fluid.
 
Continuous Measurement
SV series, Tuning-fork Vibration Method does not cause damage to the sample fluid and allows measurement of cloud point of samples such as surface active agents and of surface/interface changes such as wettability because of its excellent feature of wide measurement range without the need to replace the sensor plates.
 
Viscosity Calibration
With Viscosity Standard, viscosity calibration can be easily done. 1 point calibration of 2 point calibration is selectable in the calibration mode.
 
Data Collection and Graphing Software
WinCT-Viscosity (RsVisco) is software to import the measured data of viscosity and temperature to a PC and display graphically the changes in real-time for your analysis.
 
Small Sample Size
Standard sample cup requires the sample fluid of just more than 35 ml so you do not need to waste too much sample fluid.
 
Easy Cleaning
Due to the simple structure, the SUS 304 stainless steel sensor plates and temperature sensor (all gold-plated) and SUS 304 stainless steel protector can be easily and quickly cleaned.

Software

WinCT-Viscosity (RsVisco) software imports the measurements of viscosity and temperature, from the SV series’s built-in sensor, to a PC. It automatically displays the measurement result by graph on a real-time basis.

The scaling function is available, and the logarithm display is selectable in this function. Saving the measurement data by "CSV" file and opening it with WinCT-Viscosity is very easy and convenient for analyzing sample fluid viscosity.
