Calibrated viscometers
- For measurement of kinematic viscosity of transparent and opaque Newtonian liquids
- Meets ASTM Standard D 445; specifications conform with ASTM Standard D 446
Also used to measure kinematic viscosity of cut-back asphalts and road oils at 140°F and asphalt cements at 275°F in the range of 30 to 6000 centistokes by ASTM Standard D 2170. It is recommended that 9726A20 or A25 Constant Temperature Bath be used for work at 275°F. Can be filled and cleaned while in bath. Minimum sample volume 1 to 3 mL . Requires liquid bath depth of 230 mm. Precision: ±0.2%. Includes certificate of calibration and instruction sheet. Individually boxed. Size and serial numbers are printed on the outside of the box and on the viscometer. Unity Factor viscometer constants are within 0.2% of values listed in table preceding this series.
