For Low Temperature Pumping Viscosity of Engine Oils
The CMRV-4500 is an automated mini-rotary viscometer for measuring low-temperature pumping viscosity from –5 °C to –40 °C. It has 9 test cells. It is thermoelectrically-c
ooled via an external air/water heat exchanger.
Common Applications
Drive line lubricants
New engine oils
Used automotive oils
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
Dry gas purge regulator maintains a frost-free environment throughout the precise, microprocessor-contr
olled cooling cycle
Compact, efficient design
Benchtop unit measures yield stress and viscosity for drive line lubricants and engine oils
Solid-state thermoelectric cooling removes temperature gradients to provide significantly enhanced precision and superb temperature uniformity for all nine test cells
Compact air/water heat exchanger provides a quiet, low-maintenance system that does not rely on potentially hazardous refrigerants
High performance rotors with carbon fiber shafts minimize heat transfer in and out of test cells
Integrated drawer unit for convenient storage of CMRV accessories including rotors, weights, and cell caps.
Fully automated testing
VISCPRO® software contains pre-configured methods for each SAE-specified oil grade and referenced ASTM methods
Viscosity and yield stress are automatically calculated and saved
Versatility
Software allows custom cooling profile configuration
Optional multi-unit interface kit permits control of up to four units from a single PC
