Features:
1. Seat back endurance testing machine conforming to GB BIFMA standard;
2. Closed loop control. The output end of the cylinder is equipped with an American fatigue-grade tension pressure sensor, and the cylinder air pressure control adopts the Japanese SMC gas-electric proportional valve control, which forms a closed loop real-time control with PLC;
3. Multifunctional. The output power of the cylinder can be controlled through the touch screen (do the backrest durability test) or the output displacement (do the chair chassis back tilt mechanism durability test).
