A method and apparatus for analyzing sag in drilling fluids or solid bearing fluids wherein a cylindrical high-pressure cell assembly ( 80 ) capable of withstanding high pressure and high temperature with a coaxial cylindrical rotor ( 33 ) driven to rotate inside cell assembly ( 80 ), a sample port ( 12 ) for testing sample subtraction used for further analysis, and a sample inlet port ( 74 ) for adding testing sample. This said cell assembly ( 80 ) is supported on a pivotal cell support ( 90 ) so that it can be tilted and fixed at any angle. |
