  • Like the CMRV-5000, the CANNON CMRV-4500 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-4500 contains nine small rotary viscometers within a thermostated aluminum block. The CMRV-4500 is cooled with built-in thermoelectric modules, eliminating the need for methanol-based external refrigeration devices. The CMRV-4500 uses a compact air/water heat exchanger that circulates a mixture of coolant water and antifreeze through the instrument to cool the hot side of the thermoelectric cells. The result is a quiet, low-maintenance system without potentially hazardous refrigerants. Solid-state thermoelectric cooling provides superb temperature uniformity for all nine test cells, removing temperature gradients not only from the left to the right side of the block, but also from front to back and top to bottom. A dry gas purge includes a side-mounted flow meter with a needle-valve adjustment, the resultant dry air flow to the test environment helps improve precision and avoid condensation around the test cells.
