This fibre bundle strength tester is used in conjunction with a precision balance to provide precise, repeatable determinations of both tenacity and elongation at 1/8″ gage spacing and of tenacity at zero gage spacing.

Follows are features of fiber bundle strength tester(stelometer)

  • Calibrate each stelometer by force measuring and elongation devices that are special designed by our company only, ensure pointer indications (force value and elongation) are match to real value and keep test result stable and high accuracy;
  • Special designed table clamps and pressley clamp can hold fiber tufts effectively, and avoid slipping or affect test as hold tight;
  • Read test values of breaking strength and elongation directly from two scales after finishing test;
  • After fiber tufts breaks, there is no malfunction mistakes;
  • Test result with high accuracy and with good correlation with yarn strength.


Application of Fiber Bundle Strength Tester

Fiber Bundle Strength Tester is an instrument which breaks a flat bundle of textile fiber and indicates on graduated scales, the force required to break the bundle and the elongation of the fiber at moment of breaking. Breaking force may be converted to breaking strength (tenacity) by means of simple calculation when the length of the fibers in the bundle and the weight of the fibers are known.

Fibre Bundle Strength Tester complies with ISO 3060 etc international and retailer standards.
