Haitongda - Model MLN -Marsh Funnel Viscometer

The Haitongda Model MLN marsh funnel viscometer is a simple device for daily viscosity measurement. Funnel viscosity is the ratio of the speed of the slurry as it passes through the outlet tube (shear rate) to the force (weight of the slurry) causing the slurry to flow (shear stress). Funnel viscosity is reported as the seconds required for one quart of slurry to flow out a full funnel.
