Description

The CANNON CMRV-5000 Mini-Rotary Viscometer is designed to measure yield stress and viscosity of drive line lubricants and new and used automotive engine oils over a temperature range of
–5°C to –40°C, meeting ASTM D 4684, D 3829, D 6821 and D 6896 requirements. The CMRV instrument determines pumping viscosity in accordance with the latest SAE J300 specifications

The CMRV-5000 contains five viscometric cells machined to tight tolerances to fit the thermostated aluminum block. The cells are removable to facilitate sample handling and cleaning of cells and rotors. The CMRV-5000 provides a new level of benchtop performance in a sleek, self-contained, thermoelectrically maintained system. No accessory refrigeration units or heat exchangers are required.

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

  • 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 pings 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
