S-flow IV⁺ Kinematic Viscometer
The latest generation S-flow builds upon the proven performance of its earlier models, delivering advanced automatic viscosity testing for Newtonian samples such as petroleum products. It retains the well-established benefits of the Houillon-type tube system, including rapid analysis, minimal sample volume requirements, and reduced solvent usage, while now introducing an optional autosampler for fully unattended operation.

All functions are managed through a central user interface that handles result storage, autosampler control, viscosity index calculations, and more. The system is fully compliant with ASTM D7279, ensuring reliable correlation with ASTM D445 standards, making it highly suitable for used oil analysis laboratories that handle a wide range of lubricant viscosities.
