Product Overview

For lubricant blending facilities, commercial oil inspection laboratories, and quality assurance departments, obtaining both kinematic viscosity and fluid density under identical thermal conditions is essential for precise dynamic viscosity and viscosity index calculation. The HM-YN2 eliminates the requirement for separate standalone density apparatus, streamlining laboratory workflow. Featuring four independent measurement stations and digital interfaces including RS232, RS485, and USB, the instrument supports high sample volume routines and seamless integration with laboratory information management platforms.

Key Features

3-in-1 functional consolidation: kinematic viscosity, Ubbelohde viscosity, and liquid density determination
Generous 10-inch industrial touchscreen running an intuitive Android-based user interface
Four simultaneous testing channels providing superior multi-sample analytical throughput
Double-layer insulated glass bath design for enhanced thermal retention and operator safety
Built-in computational algorithms for automatic dynamic viscosity and viscosity index determination
German A-grade Pt100 stainless steel sensor ensuring ±0.01°C constant temperature stability
Comprehensive data communications including RS232, RS485 serial ports, and USB export capability
Active protection suite featuring bath liquid level detection and automatic overtemperature shutoff

Applications

The HM-YN2 provides multi-parameter physical testing for diverse fluid sectors:

Engine Oils & Industrial Lubricants: Kinematic viscosity at 40°C and 100°C combined with density for viscosity index (VI) certification.
Petroleum Refining: Finished fuels, light distillates, transformer dielectric fluids, and marine fuel oils.
Chemical Manufacturing: Polymer solutions, synthetic base fluids, glycols, and organic heat transfer fluids.
Research Laboratories: High-precision density-viscosity correlation studies and fluid rheology quality verification.
