Digital Paddle Viscometer Offers an Automated Alternative

The Digital Paddle Viscometer, from Cannon Instruments (USA), has been designed to provide a cost-effective and automated alternative to older, labour-intensive and less precise instrumentation and methodologies. Test data has been found to correlate well with the Saybolt viscometer method.

suspensions, marine fuels, residual oils, slurries, paints and similar materials between 30 and 30,000 centipoise (mPa·s) at temperatures of 25°C, 40°C, 50°C, 80°C, and 100°C This instrument meets ASTM D 7226 for asphalt emulsion testing. Available in two models (standard and water-cooled), the Digital Paddle Viscometer can also be used for other applications consistent with its temperature control and viscosity measurement capabilities, including the

ASTM D 244 consistency test. Ideally suited for field use, the Digital Paddle Viscometer

can determine the viscosity of lubricating oils, marine fuels and other liquids, yielding results with an accuracy of five percent or better for most materials—better than that required by ASTM D 445 for residual oils at 50°C.

centistokes (cSt or mm2/s) and Saybolt Furol Seconds if a known density value is input by the operator prior to testing. The digital display also indicates the temperature, duration of test, and test status. Test data can be transferred to the optional label printer via an RS232 connector.
