9721-R74 Nhớt kế mao dẫn Ubbelohde UBC-2B
Cannon - Mỹ
The Ubbelohde Viscometer measures kinematic viscosity of transparent Newtonian liquids according to ASTM D445 and ISO 3104. Minimum sample volume is 11 mL. Minimum bath depth is 241 mm (9.5 in). Unity factor series has a constant within +/- 0.2% of the values listed. Both calibrated and uncalibrated viscometers are available. Calibrated viscometers include a certificate of calibration and instruction sheet. Holders are sold separately.
