CMRV-4500 Mini-Rotary Viscometer
In stock
The CANNON CMRV-4500 is a semi-automated mini-rotary viscometer for measuring low-temperature pumping viscosity from –5 °C to –40 °C. It has 9 test cells and is thermoelectrically-cooled via an external air/water heat exchanger. Conforms to ASTM D4684, ASTM D3829, ASTM D6821*, ASTM D6896, SAE J300.
Common applications include drive-line lubricants, new engine oils and used automotive oils.
Protect your investment and ensure your instrument continues to provide quality and reliable results for years to come with a CANNON Service Plan.
*with drive-line motor kit
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
