yarn_package_durometer.jpg (7324 octets)

The HP models accurately measure the winding density of textile bobbins, beams, spools, spindles, cones, quills, dye packages, rolls, etc. Models HPSA and HPSD accurately measure the hardness of rubber and plastics.

FEATURES
  • Constant-pressure indicating system assures uniform test pressure eliminating false readings due to differences between operators.
  • Operation is as easy as pressing the spring-loaded knurled aluminum shell down to the red line.
  • Supplied in a foam-fitted carrying case.
