HY0331D Electronic Yarn Twist Tester is used to determine the twist of single yarns, plied yarns and all other yarns by conventional or untwist/re-twist methods. This instrument complies with the following international and industry standards: ISO 2061, BS 3356, and GB/T 2543.1. It is suitable for various yarns. Pre-tension is adjustable according to yarn categories. It adopts micro-computer control with automatic data processing, display and printout, ensuring accuracy, stability and reliability. It can also be connected to a computer to achieve more analysis functions. Equipped with an imported dedicated clock circuit, the system time can be printed on the report. The yarn holder is directly driven by a motor with stepless speed regulation; it is also designed with a speed measurement function to accurately determine the rotating speed of the yarn holder (motor). The CPU automatically judges the rotating direction of the yarn holder, processes and counts, with a division value of 1/10 twist.
