OFDA 4000

The OFDA4000 is the world's first instrument that measures length and diameter profile of fibres in top form. In one measurement using 1 minute of operator time, the values of diameter, diameter profile, curvature, length, hauteur & barbe can be determined.

Advantages:

  • Lower total cost of ownership than the 3 instruments it replaces (Fibroliner, Almeter, OFDA100 or Laserscan)
  • Labor and time saving due to one sample preparation and no operator involvement in measurement phase
  • Can measure most fibre types, including wool, cashmere, mohair, silk and many synthetic fibres.
  • Measure length as well as hauteur and barbe
  • For the first time, diameter vs. length can be automatically obtained (are long fibers broader than short fibers etc?)
  • Determination of the content of coarse fibers, which cause the prickly feeling found in certain garments
  • Can measure diameter of cut fibres in glass slides (emulate OFDA100) for measurement of non-aligned fibres
  • Blends of different fibres can be measured accurately, which is not possible using capacitance based instruments.
  • Can be purchased in modules: diameter only, length/hauteur only and upgrade later
  • Research is continuing into other measurement modules. such as neps and dark fibre.
