Evenness Tester is a universal high performance textile laboratory instrument which adopts latest electronic technology and computer technology to develop. This instrument is used to test and analyze linear density unevenness and unevenness structure character of thin yarn, roving and silver. It applies to cotton, wool, silk, flax, man-made fiber short fiber spinning and blending yarn, it is very important to improve and guarantee yarn quality.
MAIN FEATURES
Host processor adopts industrial control computer, entirely in Chinese graphic interface and convenient operation.
It can test and output CV% value, U% value and twelve level faults in real time.
It has variation-length curve, deviation ratio (DR) curve, spectrogram, linear density-frequency distribution, etc various graphic indices.
It has precise continuous spectrum which is more beneficial for user to analyze textile technical fault part.
Transmission system adopts import servo system, low noise and high reliability
Expert system can help user analyze textile technical fault bulletin and compare with USTER to evaluate spinning level.
It can store uneven curve and supply more detailed analysis for user.
