**YG021 Electronic Strength Tester for Chemical Filament Yarns**

**【Scope of Application】**  

Used for testing the breaking strength and elongation at break of synthetic fiber monofilaments, spandex, 

nylon, polyester filaments, plied yarns, and textured yarns.

**【Applicable Standards】**  

GB/T 14344, ISO 2062, GB/T 3916, ASTM D2256, DIN, BS

**【Instrument Features】**  

1. Equipped with a standard 320×240 LCD screen, test results are displayed directly.  

2. Built‑in user‑defined setting interface allows flexible parameter configuration for different specimen types.  

3. Based on the set parameter values, data can be automatically grouped and stored dynamically in the internal memory.  

4. Gauge length can be set via parameters; the main unit automatically positions itself without needing to move the positioning block.  

5. Features a timed tensile function with freely adjustable tensile time.  

6. Standard pneumatic horn‑type grips; manual horn‑type grips are available upon request.  

7. Supports computer connection and online operation; includes professional analysis software for data analysis and backup.  

8. The domestic test and data processing software uses multi‑threading, achieving truly zero‑wait testing.  

9. The software can analyze breaking point, tear point, yield point, initial modulus, elastic‑plastic deformation,

 and other data, facilitating mechanical analysis of various materials.
