Rotational Viscometers

Rotational viscometer.png

The CANNON® V-2020 viscometers are easy-to-use, affordable rotational viscometers for the determination of dynamic viscosity. they measure the viscous drag of a liquid against a rotating spindle. With available spindles, the low viscosity LV-2020 measures from 1 mPa·s (cP) to 2,000,000 mPa·s (cP) while the moderate viscosity MV-2020 measures from 100 mPa·s (cP) to 13,000,000 mPa·s (cP). Both instruments offer 18 selectable speeds ranging from 0.3 rpm to 100 rpm.

TESC.png

The compact, economical TESC (thermoelectric sample conditioner) system integrates and automates the entire ASTM D2983 conditioning and testing process for low temperature viscosity of gear oils and ATF, as well as ASTM D8210. Provides an automated alternative to ASTM D2983 sample conditioning and testing. Eliminates sample disruption during preheating, room temperature stabilization, cooling and final viscosity testing. Reduces result variability due to temperature fluctuation. Provides superior precision. Allows for unattended operation.

 

Common Applications

  • Gear oils

  • Automatic transmission fluids

Common Applications

  • Emulsified asphalts

  • Marine fuels

  • Suspensions

  • Slurries

  • Foods

  • Paints

  • Residual oils

 

The DPV is an automated, rotational digital paddle viscometer for measuring the dynamic viscosity of non-homogenous materials such as emulsified asphalts, marine fuels, residual oils, slurries and foods at 40 °C, 50 °C, 80 °C, and 100 °C. For tests at 25 °C, see the TE-DPV product page. The DPV provides an automated alternative to older, labor-intensive and less precise methods.

Ravenfield.png

The Ravenfield® by CANNON® HTHS BS/C+ Viscometer is a compact, high precision, tapered plug viscometer that measures the high temperature, high shear viscosity of engine lubricants and other oils according to ASTM D4741, CEC L-36-A-90 and IP 370 as specified by SAE J300 and ACEA. The HTHS BS/C+ Tapered Plug Viscometer also correlates to ASTM D4683 with no bias and is capable of testing across a wide range of temperatures and shear rates. Also available with an optional Model DR autosampler which permits the testing of up to 22 samples without operator intervention.

 

Common Applications

  • Engine lubricants

  • Pre-filtered used oils
