(News flash: July 2011 / PDF 93KB)
 
 
Features
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 mPas)
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
