| Product features | |||
| 1. This device is a multi-functional test device, and cylinder output force or displacement can be selected; | |||
| 2. The output Angle of the cylinder can be changed by sliding the position of the fixed pulley; | |||
| 3. The loading pad is bound to the back of the chair, and the cylinder is connected with the ribbon. After the cylinder is unloaded, the back of the chair will naturally recover to its original state by its own elasticity; | |||
| 4. Precise manual pressure regulating valve ensures stable and reliable cylinder output force, and digital display cylinder output force value; | |||
| 5. Fix the test sample with l-type gear plate and chair press plate, and keep the pressure tight with manual screws; | |||
