CANNON® Mini-Rotary Viscometer CMRV-4500 Instruction & Operation Manual
CANNON® CMRV-4500 Flyer
CMRV-4500 Mini-Rotary Viscometer
For Low Temperature Pumping Viscosity of Engine Oils
ASTM D4684, ASTM D3829, ASTM D6821*, ASTM D6896, SAE J300
The 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

Features & 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

* With optional drive line rotor kit
