Cannon® Glass Capillary Viscometers

Glass Capillary Viscometers

Why does CANNON offer so many different types of glass capillary viscometers? Primarily because no single capillary viscometer is ideally suited for all kinematic viscosity determinations. Individual analysts also have their own preferences. The tables on the right may assist you in determining which viscometer is most appropriate for your particular application.

Expanded Uncertainty

CANNON Instrument Company provides expanded uncertainty data with all of our calibrated viscometers. This is the universally accepted statistic when dealing with calibration data. In order to maintain A2LA accreditation, we are required to determine and specify the expanded uncertainty for all our calibration data. ISO publications define expanded uncertainty as "quantity defining the interval about the result of a measurement within which the values that could reasonably be attributed to the measurement may be expected to lie with a high level of confidence."

Expanded uncertainty is a more comprehensive and meaningful term than "precision" because it incorporates all variables in the measurement process. When comparing the accuracy of viscometers it is essential that the expanded uncertainty be specified. Detailed information regarding CANNON measurements and expanded uncertainty is available for download from the CANNON website, www.cannoninstrument.com.

CANNON Instrument Company also provides uncertainty data with every bottle of our certified viscosity standards.
