The Hans-Schmidt YS-105 Yarn Speed and Length Meter combines the functions of two 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 YS-105 can also be used as a contact tachometer to measure linear speeds of moving surfaces such as conveyor belts, webs of paper or fabric, etc.
