Twist Tester is a machine used to get the level of twist in single or multi-plied yarn. Our microcontroller based Twist Tester has been designed for measuring coefficient of twist in TPM or TPI. The instrument can be used on single, double, plied, woolen, jute or multi-filament yarn. It has the facility of twist and un-twist in both S/Z directions. The instrument can store up-to 20 readings at a time and provide average value. A graduated scale and spring loaded clamps makes it easier to adjust test length and mount the test specimen. Tension weights up-to 100 grams are provided with the instrument.

The Twist Tester has been designed in two models, one with fixed test length and one with adjustable test length. The slider mechanism on the adjustable model provides test length anywhere between 50mm and 500mm. The instrument provides 5 different modes of operation.
