Calibrated UBC (9721-R50) Series
For measurement of kinematic viscosity of transparent Newtonian liquids by suspended level principle as described in ASTM D 445 and D 446, and ISO 3104 and 3105. Similar to Cannon-Ubbelohde but less rugged in design. Read more about the significance of expanded uncertainty. Provided with certificate of calibration and instruction sheet.
Uncalibrated UBU (9721-N50) Series
Similar to 9721-B50 series, but uncalibrated.
Ubbelohde Unity Factor Calibrated UBXC (9721-U50) Series
Similar to 9721-R50 series, but with constant within ± 0.2% of values listed in Table below. Provided with certificate of calibration and instruction sheet.
