**【Scope of Application】**  

Used for testing the smoothness of zipper slides for metal, injection-molded, and nylon zippers.

**【Applicable Standards】**  

QB/T 2171, QB/T 2172, QB/T 2173

**【Technical Parameters】**  

1. **Test method:** Based on the international Constant Rate of Extension (CRE) principle, measures the 

maximum force when the zipper is pulled to a specified position (i.e., zipper slide smoothness).  

2. **Force measurement system:** Uses a resistance strain gauge force sensor.  

3. **Force measurement range:** 0 – 100 N  

4. **Force measurement accuracy:** ≤ ±0.2% F·S  

5. **Sample length range:** 50 – 500 mm, arbitrarily settable  

6. **Tensile speed range:** 100 – 1500 mm/min, digitally settable  

7. **Display and output:** Chinese LCD screen, data can be queried.  

8. **Data processing capacity:** ≤ 1000 tests  

9. **Power supply:** AC 220 V ±10%, 50 Hz  

10. **External dimensions:** 520 × 400 × 1600 mm  

11. **Weight:** 60 kg
