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