ISO 4913 ASTM D1447 Cotton Fiber Length Tester

APPLICATION

Cotton fiber length measuring test equipment  is used to determine cotton fiber mean length, upper half mean length and uniformity index by photo-electric method.

This instrument is designed according to random distribution theory of cotton fiber length, and the theory of that light intensity through fiber bundle has a negative relation with fiber number within fiber bundle cross section.

FEATURES

Use PC on-line technology, and get cotton fiber length shadow curve, fiber mean length, upper half mean length and uniformity index, etc.

CPU generates trigger plus to control step motor speed, and drive sampling comb with required step-size, easy to control data frequency;

High quality LED light source, sensitive silicon photocell to receive light signal, simple operation;

PC auto process data, generate fiber length curve after post-fitting, and then get cotton fiber mean length, upper half mean length, uniformity index and short fiber content;

Calibration instrument by computer, and create database ( storage, inquire, print, etc);

Special designed sampling device, easy to sample.

Fast test speed, test one test result only need 20~30s.
