Electric twist-tester 17 is a testing apparel able to measure twisting no. in S or Z of single and plied yarns in compliance with UNI EN ISO 2060, UNI EN BS ISO 2061

Twist analyses in S or Z direction of plied, multi-plied and single yarns

With proximity sensor it's easy to define precisely the end of test for untwist-retwist method according to UNI EN ISO 2060 and UNI EN ISO 2061.

View of S/Z turns no. through dial indicators

With the onboard dial indicators it is possible to have immediate check of turns no.

Left side dial indicator shows the thousands and hundreds of turn, while the right one the tenths and units.

The control board panel allows the user to switch the clamp rotation in S or Z, to select the desired test method Untwist-Retwist or Direct counting and to adjust easily rotation speed with external potentiometer during test performances.

On the left part of the unit, the elongation group inlcudes a fixed viewer scale, the elongometer, equipped with index, while the pretension set can be loaded to its dedicated support according to the yarn count (tex) of samples under examination.

The elongation scale shows clearly the behaviour of yarns during untwisting operations and it can be viewed with a double scale expressed in mm/inches.

All the elongation group can be shifted transversally by the operator along instrument basement and fixed at the desired length expressed always in mm/inches e.g. 0 - 50 cm for the standard models setting the distance length between the two yarn clamps.

Test procedures manageable with Electric twist-tester 17 are:

  • Untwist-retwist method, according to UNI EN ISO 2060
  • Direct counting method, according to UNI EN ISO 2061


  • Separation neddle, to divide the plied and multi-plied yarns during untwisting operations;
