Automated Kinematic Viscosity Systems Enhance Laboratory Precision

Core principles and standards

The instrument is designed to comply with GB/T 265, the national standard for the determination of kinematic viscosity of petroleum products and calculation of dynamic viscosity, and GB/T 1632-93, which covers the determination of viscosity number and intrinsic viscosity of dilute polymer solutions. Its core function is to analyze oils and dilute polymer solutions using Ubbelohde viscometers, with applications in metrology, scientific research and industrial production processes.

Main technical features

The system uses a microcomputer as its central control unit and provides a prompt-driven operation interface intended to simplify complex testing procedures.

• Microcomputer control: A central microcomputer unit supports a prompt-driven interface for streamlined operation.
• Automated testing sequence: The system automatically performs constant-temperature control, timing and detection, viscosity calculation, cleaning and drying of viscometer tubing, and final report output.
• Fault identification and diagnostics: Built-in diagnostic functions help users assess operating status and identify maintenance needs.

The automated workflow is intended to reduce manual intervention across the testing cycle while maintaining consistent measurement conditions.

Technical specifications

The published specifications list the instrument’s operating range and control tolerances.

Configuration and installation

The standard configuration includes four photoelectric Ubbelohde viscometer assemblies with inner diameters of 0.8 mm, 1.0 mm, 1.2 mm and 1.5 mm, covering a range of viscosity testing requirements. Custom configurations are possible for measurement ranges or viscometer types outside the standard set.

A circulating bath and vacuum suction device are not included in the standard packing list. These items must be provided separately according to the laboratory’s installation conditions.
