Used to determine the hardness/ softness of yarn bobbins/ warp beams/cones/ cheese etc.


  • Portable instrument.
  • Also called package density meter.
  • Determine density or hardness of yarn cone/package or beams of yarn or fabric.
  • Very useful in package dying & yarn dying sections as dyer can separate cones which are too loose or which are too tight.
  • Variation in package density leads to “cone to cone dye variations”.
