Ring Stiffness Tester ToronRST- Series
Ring Stiffness Tester ToronRST- Series is crafted to measure ring stiffness, ring flexibility, and creep ratio in line with relevant standards. It accommodates samples up to 3000 mm, providing precise and reliable testing capabilities for a range of applications.


Ring Stiffness Tester ToronRST- Series Features
The inner diameter measuring device continuously tracks inside diameter deformation, ensuring accurate data collection. PC-based control software allows for straightforward operation and clear visualization of results. The system applies the specified test load automatically, supported by a double-column, high-rigidity structure that enhances stability. An advanced closed-loop AC servo control system provides precise and stable control. Multiple load sensors, arranged in a bridge configuration, improve resistance to deflection in large pipes and reduce the likelihood of load sensor damage.
Application Software Features
- The modular design makes the software easy to update.
- Includes functionality for setting coordinates and saving graphs in various formats.
- An in-line calibration module simplifies the calibration process.
- Allows printing of test reports with customizable parameters.
- Free online updates keep the software current.
- Optional Creep Ratio Test: When paired with the XWW electric system, the software supports creep testing, including generating test plots, controlling and monitoring the test, analyzing data, and printing test records.
