Evenness tester for Testing & Quality Control Department
Evenness tester for Testing & Quality Control Department of a Textile Engineering College
- Evenness tester is designed to measure with high accuracy the mass evenness and imperfections of the yarn.
- Stands up for the high quality capacitive sensor which is suitable to test yarns, roving and slivers without need of another external sensor.
- Capacitance Based, Suitable for 4 Tex to 40 K Tex spun yarn.
