Product Overview
The HM-WYN Low-Temperature Kinematic Viscosity Tester is specifically engineered for viscosity measurements across a broadened thermal spectrum from 5°C to +100°C. Unlike standard high-temperature baths that depend on external recirculating chillers for sub-ambient measurements, the HM-WYN integrates a direct immersion compressor refrigeration system that achieves rapid chilling down to 5°C with zero requirement for external plumbing or auxiliary chillers. Accommodating both Ubbelohde and Pinkevitch viscometer tubes across four testing channels, it features German Pt100 thermal sensing, ±0.01°C temperature regulation, and a 7-inch industrial touchscreen.
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.
