To determine and analyze sliver, roving and spun yarn’s evenness and the 
	evenness of structure . Applicable to silver, roving and spun yarn made of 
	cotton, wool, synthetic fiber, linen and blended yarn, etc. 
	Drawing mechanism adopts dual-motor drive mode to achieve non-silp of 
	sliver. Large size of roller to lower rotate speed with unique aseismic design 
	and more stable transmission. Roller is available for auto open-close, auto 
	scaling, and can be used in revising direction, which reduces the abrasion 
	for roller from yarn, and extend service life of roller. 
	Wave spectrogram can display wavelength value, unevenness curve can be 
	scaled freely. With larger data retrieval function. 
	
	
	1. Can measure the unevenness of roving, sliver. 
	2. Automatic zero, and automatic adjust average, operation more convenient, 
	more efficient. 
	3. The unevenness curve can be saved, playback, and mark defect position on 
	the uneven curve. 
	4. Automatic alarm when sliver break off during testing. 
	5. Powerful statistical analysis, providing annual and monthly product quality 
	analysis and quality trend in graphic , provides the basis reference for
	scientific management users. 
	6. Using a graphical interface, cooperate with control panel key board to
	achieve complete testing by a key operation.
