LARAY VISCOMETER

A laboratory instrument for measuring the viscosity and yield value of paste inks and other high viscosity materials. Sometimes referred to as a “falling rod viscometer”, the Laray involves a weighted rod that passes vertically through a precisely matched orifice covered with the test material. The time required for the rod to move a specified distance through the test material helps determine the viscosity & yield value of the material. Various weights can be added to the rod, and multiple drop times can be factored for better characterization of the material being tested.
