Stress Relaxometer
High-Precision Stress Relaxometer for Accurate Stress Relaxation Testing
The Stress Relaxometer is specially designed to evaluate the stress relaxation properties of prestressed steel materials under constant strain conditions. It accurately measures the reduction of stress over a specified period, helping manufacturers verify the long-term mechanical performance and durability of materials.
Widely used in prestressed steel wire and strand manufacturers, quality inspection laboratories, construction material testing centers, universities, and research institutes, the machine delivers reliable, repeatable, and standards-compliant testing results.

Working Principle
The Stress Relaxometer applies a predetermined tensile load to the specimen and maintains a constant elongation (strain) throughout the test.
As the material naturally relaxes over time, the internal stress gradually decreases. The machine continuously monitors the stress reduction using high-precision load sensors and automatically records stress values throughout the testing period.
The testing software calculates stress relaxation values and generates detailed reports according to the selected testing standards, providing accurate data for material evaluation and quality control.
