INCLUDES: RHEOSYS MERLIN II USER MANUAL AUG 2008 VOL.1 ISS.2 MERLIN II OVERVIEW. THE MERLIN II IS A PROGRAMMABLE CONTROLLED SHEAR RATE RHEOMETER / VISCOMETER WITH INTEGRATED TEMPERATURE CONTROL AND AUTOMATED TEST CAPABILITIES. THE MERLIN II MEASURES FLUID PARAMETERS OF SHEAR STRESS AND VISCOSITY AT GIVEN SHEAR RATES. VISCOSITY IS A MEASURE OF A FLUID'S RESISTANCE TO FLOW. THE PRINCIPLE OF OPERATION OF THE MERLIN II IS TO DRIVE A SPINDLE ( WHICH IS IMMERSED IN THE TEST FLUID) AT THE SET SPEED WITH A HIGH DEGREE OF ACCURACY. THE VISCOUS DRAG OF THE FLUID AGAINST THE SPINDLE IS MEASURED BY THE CURRENT REQUIRED TO MAINTAIN THE ROTATIONAL SPEED. THE CURRENT IS MEASURED WITH A HIGH RESOLUTION CURRENT SENSING TRANSDUCER. THE MEASURING RANGE OF THE MERLIN II( IN CENTIPOISES) IS DETERMINED BY THE ROTATIONAL SPEED OF THE SPINDLE THE SIZE AND SHAPE OF THE SPINDLE THE CONTAINER THE SPINDLE IS ROTATING IN AND THE FULL SCALE TORQUE RANGE.
