Brand: Jiubin
Name: Microcomputer controlled steel strand relaxation testing machine
1、 Main functional purpose：

Mainly used to test the tensile stress relaxation performance of prestressed steel wires, steel bars, steel strands, and prestressed steel bars at room temperature. Suitable for testing materials in industries such as highway bridges, construction engineering, metrology and quality inspection, research institutes, metallurgy and steel.

The machine has stable loading, accurate control, low noise, and good long-term stability.

◆ It has a relationship curve between residual test force or relaxation rate and time, as well as a relationship curve between temperature and time.

The stress relaxation performance of the specimen can be calculated for 1000 hours.

◆ It can automatically calculate the stress relaxation performance (such as stress relaxation rate) of the specimen and print out the complete test report.

Both load and displacement are calibrated digitally.

◆ It has the function of storing test results, viewing and traversing the test process.

◆ The coordinate size can be automatically adjusted, and the entire testing process always displays the complete curve.

The experimental parameters can be automatically stored, retrieved, and set.

After the experiment is completed, you can use the mouse to pick up data on the test curve.
