Electronic Semi-Automatic Twist Tester "TWISTRONIC" - Code 2530A 

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.
• RS232C serial port.
