Short Guide to the Tuning Fork Vibro Rheometer: RV-10000A
(PDF 1.31MB)
-
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
Controller section
-
User calibration function, including a simplified calibration using purified water
-
Sample fluid temperature control using the provided water jacket
-
Anti-corrosive, titanium sensor plates and temperature sensor
-
X-Y-Z stage, anti-vibration table (AD-1671A), positioning stopper, etc., as standard accessories
- RS-232C interface
USB (1.1) interface
