Introduction of product:

This tester is designed for the test of the zig-zag spring assembly and spring pack used in sofa manufacturing; it can perform the following 3 kinds of test requirements:

1) Durability Test

The spring undergone a repeated specific force, the test cycles is pre-settable, and the test stop when the set cycle is up.

2) Fix stroke test

The presser comes down to a specify stoke, read the force on that stroke from the pressure gauge.

3) Fix force test

The presser comes down to a specify force, the presser stop and the compression rate (stroke) will be displayed on the screen.

Specialize using in testing the durability and endure of sofa's spring frame and spring pack.
