HY-S300 Automatic Filament Strength Tester is used to determine the breaking load and extension of single yarns and threads, such as cotton, wool, jute, silk, chemical fibre, etc. Fully automatic test to clamp yarn, save labor and time. Independent of the modular design, each test module is relatively independent of the test unit, easy to use, maintenance and upgrading. Our machine can add yarn count test parts, twist parts (for multifilament). Servo motor drive, equipped with position sensor to make sure test result is accurate. Changeable load cell to perform more test request. Various sample clamp for yarn, filament, multifilament etc. Automatically save data while power down. Easy to change load cell without recalibration. Shortcuts to make operate more easy.
