【Scope of application】
1. The digital automatic yarn length measuring instrument is a precision instrument for measuring the length under the standard tension of yarn removal, which is mainly suitable for measuring the length of wool wool fabrics, wool knitted fabrics and yarn before weaving, so as to calculate their linear density and knitting density coefficient; and the determination of elasticity and shrinkage of elastic yarn and expanded yarn. 2. This instrument adopts the principle of constant load to conduct tensile tests on the specimen. This instrument adopts isokinetic elongation (CRE) detection mechanism, microcomputer control, large screen LCD display, automatic data processing, and can be printed out, easy to set up the program, accurate and fast testing.
【Relevant Standards】
FZ/T01091、FZ/T01152、FZ/T01093、GB/T29256.5-2012；
