Zeitfuchs Cross-Arm Viscometer, Size 5

Zeitfuchs Cross-Arm Viscometer, Size 5

The Zeitfuchs Cross-Arm Viscometer (Size 5) is a specialized laboratory instrument designed for the precise measurement of kinematic viscosity in transparent and opaque liquids. It is particularly well-suited for testing asphalt binders, bitumen, and road oils at elevated temperatures, such as 140°F (60°C) and 275°F (135°C), in compliance with industry standards.

This specific Size 5 model is designed for a viscosity range of 60 to 300 centistokes (cSt), with an approximate constant of 0.3 cSt/s. It delivers highly accurate results, with a measurement precision of ±0.2% within its stated range.

A key design advantage of the Zeitfuchs Cross-Arm Viscometer is its operational efficiency. It requires a small sample volume of only 1 to 3mL, which minimizes waste and reduces testing time. Furthermore, its unique cross-arm structure allows for filling and cleaning while the viscometer remains immersed in a constant temperature bath, streamlining the workflow and ensuring stable temperature conditions during testing. A minimum bath immersion depth of 9in (230mm) is required for proper operation.

Each viscometer is meticulously calibrated and supplied with a Certificate of Calibration, guaranteeing its accuracy and traceability.
