High Precision Hand Operated Twist Tester - Code 2530D
Suitable for both single and twisted yarns (S & Z).
Digital reading. Original model complete with optical tracer and warning light to signal the starting and stopping "zero".
Accuracy: +/1 rotation.
Highly sensitive "Elongation" indicator with built-in rapid clamp.
Clamp and handle rotation ratio 10 : 1.
Adjustable distance between clamps from 0 to 50 cm and from 0 to 20 inches.
Electric Twist Tester - Code 2530C
Adjustable speed of the rotating clamp by means of
a special electronic variator. Digital reading. Suitable for both single and twisted yarns (S & Z) up to 9999 torsions. High sensitivity pretensioning device with built-in electric clamp for the seizing of yarn.
Complete with optical tracer and warning light to
signal the starting and stopping "zero". Adjustable distance between clamps from 0 to 50 cm and from 0 to 20 inches.
Suitable to determine twist of both single, twisted and Open End yarns. The principle characteristics of this model are:
Automatic and pneumatic yarn clamping system once the correct pretensioning is reached.
Automatic start-up following clamping.
Complete with software and integrated printer which provide the analysis and printout of the following data: mean value, min. value, max. value, coefficient of variation %, range and standard variation.
Three preselection text methods: 1.) Traditional Method: untwisting, retwisting for single yarns. 2.) "Schutz" Method: untwisting, retwisting, and double counter-check. This test is used mainly on O.E. spun and worsted wool yarns. 3.) Direct Method: untwisting for plied yarns, threads and multi-filament yarns.
