17853698681Product details
Product Overview
Fluids operating under extreme environmental conditions—such as aviation kerosene, refrigeration lubricants, engine coolants, transformer fluids in arctic zones, and diluted polymer solutions—must be characterized at low temperatures to ensure against crystallization, excessive pump drag, or shear failure. The HM-WYN provides petroleum and industrial laboratories with a self-contained low-temperature testing platform. The instrument includes safety interlocks that automatically disable heating elements when bath fluid falls below safe operational levels.
Key Features
- Integrated compressor cooling module achieving rapid refrigeration down to 5°C without external water loop
- Broadened thermal operating window spanning 5°C to +100°C with ±0.01°C temperature stability
- Four experimental testing channels enabling concurrent multi-sample viscometric determinations
- Versatile dual-method support accommodating both Pinkevitch and Ubbelohde capillary viscometers
- German A-grade Pt100 stainless steel temperature probe with integrated multi-point calibration logic
- 7-inch industrial color touchscreen delivering clear parameter monitoring and test management
- Safety interlock architecture incorporating bath liquid level protection and overtemperature shutdown
- Built-in thermal printing subsystem supporting immediate on-site test record generation
Applications
The HM-WYN serves specialized low-temperature and ambient fluid evaluation needs:
- Aviation & Aerospace: Jet fuel low-temperature fluidity, turbine oils, and aviation hydraulic fluids.
- Refrigeration Industry: Refrigerant-oil miscibility testing and refrigeration compressor oils.
- Automotive & Transport: Antifreeze coolants, low-viscosity synthetic transmission oils, and brake fluids.
- Polymer & Chemical Testing: Ubbelohde intrinsic viscosity determination for polymers in organic/aqueous solvents.
- General Petrochemicals: Pour point-adjacent viscosity determination and base oil blending verification.

Related Models
For standard temperature testing (ambient to +150°C) where refrigeration is not required, consider the cost-effective HM-YN1 or the 3-in-1 HM-YN2 (adding density measurement). If your laboratory requires full automation with automated sample suction and tube washing, explore the HM-YN3 series.
