Mini-Rotary Viscometer

Determines the measurement of the Yield Stress, Apparent Viscosity and Borderline Pumping Temperature (BPT) of engine oils. Borderline pumping temperature is a measure of the lowest temperature at which an engine oil can be continuously and adequately supplied to the oil pump inlet of an automotive engine. Provides a correlation between the temperature at which the viscosity of engine oils reaches a critical value and the borderline pumping failure temperature in engines at the test method specified shear stress. Testing capacity of up to 10 samples Microprocessor temperature controllers store all testing profiles in memory Unique design is fully self-contained - no external refrigeration or heating apparatus needed Advanced direct refrigeration technology eliminates the need for liquid cooling mediums such as methanol Removable test cells allow for easy cleaning, sample agitation and advance sample preparation New rotor design eliminates possible interference with water and ice Internal hermetic refrigeration system provides direct instant cooling Power-saver feature allows testing profile to resume in the event of a brief power interruption Internal gas system provides a continuous blanket of dry gas over samples to eliminate moisture buildup Rotor stator rack supplied for convenient cleaning, drying, and storage Safety features include high pressure cutout and high temperature limits 5 Rotor stator sets required for instrument. Additional sets up to 10 available Software Package Required Rotor/Stator Holding Rack Stator Insertion/Removal Tool Moisture Cover Set of Weights and Strings
