YG821L Zipper Lightness Tester |
【Scope of application】 It is used to test the lightness of zippers of metal, injection molding and nylon zippers. 【Standards compliant】 QB/T 2171, QB/T 2172, QB/T 2173 【technical parameter】 1. Test method: According to the internationally preferred principle of constant velocity elongation (CRE), the force value of the zipper when the zipper is closed to the specified position (that is, the light slip of the zipper) is measured 2. Force measuring system: using resistance strain load cell 3. Force measuring range: 0~100N 4. Force measuring 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 capacity: ≤1000 tests 10. Power supply: Ac220V±10% 50Hz 11.
