【Scope of application】:Zipper slippage testing for metal, injection molded, nylon zippers. [Meet the standard]:QB/T 2171、QB/T 2172、QB/T 2173 【Technical Parameters】: 1. Test method: According to the international constant velocity elongation (CRE) principle, the maximum force value when the zipper is pulled to the specified position (i.e., the zipper lightness and slippage) is measured 2. Force measurement system: use resistance strain force sensor 3. Force measurement range: 0~100N 4. Force measurement accuracy: ≤±0.2% F•S 5. Sampling length: 50-500mm arbitrarily set 6. Stretching speed: 100~1500mm/min digital setting 7. Display output: Chinese LCD screen, data can be queried 9. Data processing volume: ≤ 1000 tests 10. Power supply: Ac220V±10% 50Hz 11. Overall dimensions: 520×400×1600mm 12. Weight: 60Kg
