YG137 Capacitance-type Yarn Evenness Tester Used for testing the yarn,sliver and roving’s evenness the structure of evenness.its suitable to sliver and roving made of cotton wool,synthetic fiber,jute and blending.This kind of instrument uses the latest computer technology and high-speed digital signal process (DSP) technology,analyzing number of fault.Meanwhile,it displays the instantaneous uneven figure in the screen,and delivers spectrogram to judge the situation of apparatus or the trouble parts.it has the advanced technology,strong function and good steadily.The evenness testing system of yarn can be connected with any other capacitance-type testing instrument,considerably matching each other and the structure is simple,which change the paralytic evenness instrument of yarn into a entirely new apperance,becoming in a new,advanced and reliable evenness Standards:GB/T3292.
