Product Overview
Six-Speed Rotational Viscometer for Drilling Fluid Rheology
The OMNI 6110 measures the rheology of drilling fluids and other laboratory liquids at six standard speeds. Electronic speed control replaces mechanical gear shifting for better long-term stability and repeatability.
Multi-point readings let you plot rheology curves and evaluate non-Newtonian fluids, including apparent viscosity, plastic viscosity, yield point, gel strength, flow behavior index, and consistency coefficient.
Key Features
- Six standard speeds: 3, 6, 100, 200, 300, and 600 rpm.
- Push-button speed selection with electronic speed control.
- Large dial display that is easy to read under varied lab lighting.
- Low-drift circuitry and stable motor performance over long runs.
- Standard torque spring for conventional dial-reading conversion.
- Includes stainless sample cup and measuring assembly.
