CMRV-5000 Mini-Rotary Viscometer
The semi-automated CANNON CMRV-5000 is a compact and completely self-contained mini-rotary viscometer for measuring low temperature pumping viscosity from –5 °C to –40 °C. It comes with five removable test cells and offers integrated thermoelectric air-cooling. Meets requirements of ASTM D4684, ASTM D3829, ASTM D6821*, ASTM D6896 and SAE J300. 

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

  • Completely self-contained benchtop unit for measuring yield stress and viscosity for drive line lubricants and engine oils
  • Thermoelectrically air-cooled unit requires no external refrigeration or heat exchangers,eliminating the need for potentially hazardous refrigerants
  • Environmentally friendly (no freon gas),solid-state thermoelectric cooling removes temperature gradients to provide significantly enhanced precision and uniform temperature across all 5 test cells
  • High performance rotors with locking pins and carbon fiber shafts minimize test cell heat transfer
  • Five removable test cells allow for easy cleaning and sample handling

Fully 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

* With optional drive line rotor kit
