Zhuozhou Tianpeng Imp. and Exp. Trade Co., Ltd. is one of the leading manufacturers and suppliers of dynamic shear rheometer dsr in China. With abundant experience, we warmly welcome you to buy customized dynamic shear rheometer dsr made in China here from our factory. Quality products and reasonable price are available.
Description of Product
The equipment measures the dynamic shear modulus G* and phase angle δ of bitumen across a temperature spectrum of 5-85℃. From these measurements, it determines the viscous and elastic characteristics of both aged and unaged asphalt samples, enabling accurate prediction of their performance against rutting and fatigue cracking.
APPLICATION
Suitable for a wide range of materials including asphalt, coatings, food, cosmetics, polymers, adhesives, medicine, and composite materials.
CONFIGURATION
Includes main unit, temperature control (circulation) system, asphalt fixtures (8mm and 25mm), and dedicated asphalt test software.
Standards
-
ASTM P246
- AASHTO T31

Features
● Ultra-low inertia hollow cup servo motor enables smooth positioning and speed regulation with fast torque and speed response, while maintaining an absolute linear relationship between current and torque, voltage and speed.
● High-precision optical encoder (10⁻⁴ rad resolution) measures rotational angular displacement and velocity, complemented by ultra-sensitive normal force and torque sensors for fast transient response and accurate measurement, plus a grating system with 0.1 µm vertical positioning resolution.
● Peltier temperature control system with embedded high-resolution sensor ensures rapid and accurate sample temperature management, featuring one-step plug-in design for power, communication and fluid connections.
● All mechanical, power, control, communication and display components are integrated into one compact unit, demanding high standards in design, processing and assembly.
● Intelligent software with user-friendly interface covers all DSR test parameters including fixture, temperature and test settings, minimizing operator influence and supporting Time-Temperature Superposition (TTS) for master curve generation.
