The new Mini Rotary Viscometer
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 CANNON 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 for this innovative redesign of the reliable CANNON Mini-Rotary Viscometer series. Like its predecessor units, the CMRV-5000 provides reliable and accurate temperature control, meeting all requirements of the relevant methods. High-performance rotors are manufactured with carbon fibre shafts, minimizing heat transfer in and out of the test cells. 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. A Plexiglas cover includes a molded inlet port for tubing from the dry gas purge regulator, which assists in maintaining a frost-free environment around the cells during the cooling phase of the test. A built-in microprocessor controls temperature throughout the precisely controlled cooling cycle. At the conclusion of the cycle, the viscosity and yield stress are determined using an electronic timing mechanism coupled to a pulley wheel assembly that measures rotor rotation as constant torque is applied.
