YSL-2000HD Multi-function Yarn Speed & Length Meter

Click images to enlarge.
The CHECK-LINE YSL-2000HD combines the functions of three separate instruments in one, easy-to-use device.

It accurately measures the speed and length of yarns, and other filaments using a unique "wrapper" roller. This precision roller directs the filament onto the low-inertia, U-grooved measuring wheel to maximize contact and eliminate filament slip and breakage.

The YSL-2000HD can also be used as either a contact or non-contact tachometer to measure rotational speeds of shafts, motors, pulleys, etc. or linear speeds of moving surfaces such as conveyor belts, webs of paper or fabric, etc.


  • Slide-on measuring heads make it simple to rapidly convert from one function to another
  • Accuracy of ± 0.02%
  • Built-in memory for last, maximum, minimum values
  • NIST-Traceable Certification Included
  • 5 Year Warranty
