Rheology, the science of how materials flow and deform, relies on two fundamental measurements: the strain applied to a material, and the material’s response. Together, these measurements reveal the complex behaviors of a variety of materials ranging from low viscosity fluids to rigid composites under different conditions.

Separate Motor and Transducer (SMT) Technology
The ARES-G3 Rheometer’s SMT design sets a new benchmark in precision by decoupling the motor from the measurement, eliminating common calibration protocols and uncovering nuanced material behaviors that standard systems often miss. This independence is especially valuable for high-fidelity deformation testing like large amplitude oscillatory strain (LAOS), and for evaluating soft or complex materials such as emulsions and polymers under challenging conditions.
At the core of SMT lies the force rebalanced transducer (FRT), which stays motionless and captures the sample’s true response with minimal disruption from motor dynamics. When paired with the powerful drive motor, it delivers cleaner data free from typical mechanical noise, giving researchers greater confidence in their rheological insights.
