Rheometers & Viscometers


A&D’s unique Tuning-fork Vibration method promises high accuracy and a wide measurement range without replacing the sensor plates

Tuning Fork Vibro Rheometer

Repeatability as high as 1% of the measured value (by S.D.) even with low viscosity sample fluids
Shear rate changes by controlling the sensor plate vibration amplitude
Easy setup/cleaning and very quick measurement (stabilization in 20 seconds)
Wide continuous measurement range (max. 0.3 to 25,000 mPa·s)
Little interference to the sample fluid
Possible to measure fluids in motion
Comes with a special controller for:
– Automatically changing the amplitude (shear rate) and capturing data in the manner set by the user
– Real-time graphing of viscosity variation with time, temperature, as well as shear rate
– Saving results (in CSV format) and graph screens (as JPEG images) in USB flash drives

SV-A Series Tuning Fork Vibro Viscometers


Wide-range, continuous measurement without replacing the sensor plates
Simultaneous measurements of temperature and viscosity
Windows Communication Tools WinCT-Viscosity and a serial-USB converter provided as standard
Easy set up and very quick measurement
Excellent repeatability (1% of the measured value by standard deviation)
Extremely high sensitivity (detects a viscosity as low as 0.3 mPa·s)
Little interference to the sample fluid
Possible to measure fluids in motion
Simplified calibration function (for SV-1A and SV-10A)
Easy cleaning after measurement
