Cannon Zeitfuchs Cross-Arm Viscometer (Reversed Flow)
ASTM D445, ASTM D2170, ISO 3104
The Zeitfuchs® Cross-Arm Viscometer is designed to measure the kinematic viscosity of both transparent and opaque Newtonian liquids according to ASTM D445 and ISO 3104 standards. The viscometer allows for easy filling and cleaning without the need to remove it from the constant temperature bath. It requires a minimum sample volume of 1 mL to 3 mL and a bath depth of at least 230 mm (9 inches). The Unity Factor series has a constant accuracy within ± 0.2% of the listed values. Each viscometer comes with a certificate of calibration and an instruction sheet, and it includes or offers separately, permanently attached round or rectangular metal holders.
This viscometer is also suitable for measuring the kinematic viscosity of liquid (cutback) asphalts and road oils according to ASTM D2170.
