This is an instrument used to determine the consistency of viscous materials by measuring the distance that the material flows under its own weight in a given time interval. The instrument allows producers of such viscous products to predetermine formulas for their product and to standardise production lots.

This product is made from 316 stainless steel (food grade) stain-resistant material, to ASTM F1080 – 93 It consists of a trough divided into two sections by a gate. The smaller section serves as a reservoir for the material to be tested. The larger has laser etched graduated measurement lines along the bottom in one centimetre divisions beginning at the gate. The gate is spring-operated and is held by a trigger that permits instantaneous release. In operation, the gate slides vertically in the grooves of two posts extending upward from the sides of the trough. The L-shaped trigger release hooks over the top of the gate to hold it in a closed position. Two levelling screws are located at the reservoir end of the trough and a circular spirit level is located at the other end of the trough.
