Overview
The ARES-G3™ rheometer integrates Separate Motor and Transducer (SMT) architecture with a Force Rebalanced Transducer (FRT) to measure true material response across oscillatory, steady shear and extensional tests. Designed for industrial rheology applications, it delivers high-resolution torque and strain data while minimizing motor-induced measurement artifacts.

Key features

• SMT architecture: Decoupled motor drive and transducer reduce mechanical interference and lower calibration frequency.
• Force Rebalanced Transducer (FRT): Motionless transducer records cleaner torque and phase signals for sensitive materials.
• High sensitivity and dynamic range: Very low torque resolution and fine strain resolution suited to soft materials and LAOS testing.
• Dual data acquisition: Simultaneous capture of complementary signals at high rates improves data density and low-frequency accuracy.
• Fast Frequency Chirps: Optimized chirp methods accelerate frequency sweeps and time–temperature superposition workflows.
• Modular platform: Scalable core supports SmartSwap accessories and future measurement modules.

Engineered capabilities

• Temperature control: Forced Convection Oven (FCO) and Advanced Peltier System (APS) for broad and precise temperature ranges.
• Measurement modes: Oscillatory, steady shear, extensional rheology, orthogonal superposition (OSP), cone-partition-plate and simultaneous measurement techniques (dielectric, electric field, UV).
• Rapid control: High-performance drive motor enables complex deformation waveforms and fast step changes in velocity/strain.

Technology highlights

• SMT design: Isolates actuation from measurement to reveal nuanced material responses, especially for soft, complex and LAOS studies.
• FRT measurement: Motionless transducer captures true sample stress with minimal motor noise.
• Integrated methods: Time-resolved mechanical spectroscopy (Fast Frequency Chirps) for dense, reliable frequency-domain data.

Applications

• Thermoset curing and gelation monitoring.
• Complex fluids such as emulsions, suspensions and slurries.
• Polymer melts and processing-related rheology.
• Composites, coatings, adhesives and advanced material development.

Accessories & extended capabilities

• Forced Convection Oven (FCO) for extended temperature ranges and improved oxygen exclusion.
• Advanced Peltier System (APS) for fast-response sub-ambient to elevated control.
• SmartSwap-compatible modules: environmental enclosures, OSP, simultaneous measurement units and more.
