Material and Chemical Resistance of the Sensor Part

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 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

External Input / Output

RS-232C interface
USB (1.1) interface
