Máy Đo Độ Nhớt Quay CMRV-4500

FEATURES AND BENEFITS

Reliable and accurate results

• Meets requirements of ASTM D4684, ASTM D3829, ASTM D6821* and ASTM D6896
• Meets latest SAE J300 specifications for low-temperature pumpability
• Reliable and accurate temperature control from −5 °C to −40 °C
• High resolution optical encoder for digital detection of yield stress and viscosity
• Dry gas purge regulator maintains a frost-free environment throughout the precise, microprocessor-controlled cooling cycle

Compact, efficient design

• Benchtop unit measures yield stress and viscosity of drive line lubricants and engine oils
• Environmentally-friendly (no freon gas), solid-state thermoelectric cooling removes temperature gradients to provide enhanced precision and uniform temperature across all 9 test cells
• Air/water heat exchanger provides a quiet,low-maintenance system without a need for potentially hazardous refrigerants
• High performance rotors with locking pins and carbon fiber shafts minimize test cell heat transfer
• Integrated drawer unit for convenient storage of CMRV accessories including rotors, weights, and cell caps.

Semi-automated testing

• Windows®-based VISCPRO® software offers preconfigured profiles for each SAE-specified oil grade and referenced ASTM method as well as the option for custom cooling profile configuration
• Software provides graphical representation of cooling profiles
• Viscosity and yield stress are automatically calculated and stored or exported via built-in LIMS output
• Optional multi-unit interface kit permits networking and control of up to four CMRV units from a single PC
