SV-10 Series Sine-wave Vibro Viscometer
Viscometery Revolution !
Viscometer SV-10 / SV-100
Newly developed Tuning-fork Vibration Method* promises you high accuracy and wide measurement range without replacing sensor plates!! *Patent pending. Sine-wave Vibro Viscometer SV-10/SV-100 measures viscosity by detecting the driving electric current necessary to resonate the two sensor plates at constant frequency of 30Hz and amplitude of less than 1mm.

  • High Measurement Accuracy
    Tuning-fork Vibration Method turns into reality for excellent repeatability of 1% of reading for viscosity measurement by Sine-wave Vibro Viscometer SV-10 / SV-100.
  • Selectable Wide Measurement Range
    Sample with Low viscosity to high viscosity can be measured without changing the sensor plates, so a wide range of measurements can be made continuously. SV-10: 0.3 - 10,000 mPa・s ( cP) SV-100: 1000 - 100,000 mPa・s ( cP)
  • Real-Time Measurement
    The sensor plate for the SV series is of a thin and small size, in area and in mass, making it is 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.
  • 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 and the detection unit (sensor plates) with small surface area/thermal capacity reach the thermal equilibrium in only a few seconds.
  • 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 for 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 or 2 points calibration is selectable in the calibration mode.
  • Non-Newtonian Sample Viscosity Measurement
    Thin sensor plates allow little deformation of sample texture and thus enable measurement of stable viscosity values.
  • Foaming Sample Measurement
    Low drive frequency of 30Hz allows measurement of foaming samples without breaking minute foams and with less influence scattering larger foams.
  • Flowing Sample Measurement
    Even the viscosity of flowing samples can be measured, including liquid in turbulent flow, which enables field management with identical data used at the laboratories.
  • Separated type model
    SV series is composed of the Display Unit and Main Unit offering excellent placement flexibility.
  • Vacuum Fluorescent Display
    You can avoid unnecessary reading errors with easy-to-read, large, clear display: 13mm height for viscosity measurement and 11mm height for temperature measurement.
  • 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.
  • Sol and Gel Measurement
    Sol and Gel sample fluid like a starch can be measured during the change of material characteristic.
  • Standard RS-232C Interface
    The RS-232C comes standard for your PC or Printer connectivity and the connection cable (25 pin - 9 pin) is also standard accessory for your convenience
  • 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.
