Viscosity and Rheology Testing


Brookfield DV-III Wells Cone and Plate Rheometer


The Wells-Brookfield Cone/Plate Viscometer/Rheometer is a precise torque meter which is driven at discrete rotational speeds. The torque measuring system, which consists of a calibrated beryllium-copper spring connecting the drive mechanism to a rotating cone, senses the resistance to rotation caused by the presence of sample fluid between the cone and a stationary flat plate.


The system is accurate to within ±1.0% of the working range. Reproducibility is to within ±0.2%. Working temperature range is from 0°C to 100°C.
