Computer Controlled Torque Rheostat Tester
Category：Universal Strength Tester
Introduction
The Computer Controlled Torque Rheostat Tester simulates industrial mixing on a lab scale. A material sample in a heated chamber with rotating blades generates torque as it resists rotor motion. A transducer measures this torque in real-time. The computer controls chamber temperature and rotor speed per a test profile, presenting data as a torque-time curve for analyzing material behavior.
Application
Materials Science: An ideal instrument for studying the flow, plasticity, thermal, and shear stability of materials.
Food Industry: Used to test the rheological properties of food materials, such as the mixing of multi-component materials, the cross-linking and curing of thermosetting resins, and the vulcanization of elastomers.
Chemical Industry: Used to study the rheological characteristics of chemical materials, such as the rheological properties of polymer melts, suspensions, coatings, inks, and food.
Geological Engineering: Used for rheological characterization of geological materials, such as the flow and deformation characteristics of rocks and soils.
