Model YG020B Electronic Single Yarn Strength Tester is one which is controlled by the microcomputer, driven by the stepping motor and working according to the principle of the constant rate of extension (CRE). It can be used to measure the tensile strength, the break elongation as well as the length under constant force, the force under constant length of yarns of cotton, wool, silk, ramie and chemical fiber etc., and the measured data can be printed out by the printer after mathematical statistics, or be connected with PC to make communication (additional order).

The principle and features of the tester are in accordance with the international standard ISO2062-1993 Methods to Measure Break Load and Break Elongation of Single Yarn and the national standard GB/T3916 Measurement of Break Strength and Break Elongation Rate of Singe Yarn Package Yarn Textile.
