Glass Viscometer

Primarily because no single capillary viscometer is ideally suited for all kinematic viscosity determinations. Individual analysts also have their own preferences. Instead of listing the precision of our glass capillary Viscometers, we now provide the expanded uncertainty. This is the universally accepted statistic when dealing with calibration data. Our use of expanded uncertainty instead of precision does not reflect any change in the accuracy or quality of our viscometer. It is a statistical term that is more comprehensive than precision. When comparing the accuracy of viscometers it is essential that the expanded uncertainty be specified.
