ZCAC- 4 Zeitfuchs Cross-Arm CALIBRATED

The Zeitfuchs Cross-Arm Viscometer measures kinematic viscosity of transparent and opaque Newtonian liquids according to ASTM D445 and ISO 3104. It can also be used to measure kinematic viscosity of liquid (cutback) asphalts and road oils at 60 °C (140 °F) and asphalt cements at 135 °C (275 °F) according to ASTM D2170. 

Filling and cleaning does not require removal from the constant temperature bath.

Minimum sample volume is 1–3 mL. Minimum bath depth is 230 mm (9 in).

Viscometer is calibrated at 40 °C and provided with a certificate of calibration and instruction sheet. See expanded uncertainty for more information.

Viscometer constant is the same at all temperatures. Approximate constant is 0.1 cSt/s. Viscosity range is 20–100 cSt (represents flow times of 200–1000 seconds).
Unity Factor Viscometer (constant within ± 0.2% of value listed above) is also available, see 9723-U59.

Holders are sold separately. For holders, see 9726-M95 and 9726-M98.
Viscometer with permanently attached holder is also available. See 9723-W59 and 9724-B59.
