Marsh Funnel

The Marsh Funnel provides quick measurements for reporting mud consistency. Fluid viscosity if the ratio of speed of the sample as it passes through the outlet tube (shear rate) to the amount of force (fluid weight) that is causing the fluid to flow (shear stress). Frequent reporting will show viscosity changes that would require corrective action.

Break-resistant plastic holds shape with temperature changes and transports easily for use in the field.
