Special Features

The yarn speed and length meter YS-20 combines the function of four separate instruments in one:
– Speed and length meter
– contact measuring of revolutions
– contact measuring of velocity of rotation
– non-contact measuring of revolutions

2 Slide-in measuring adapters for yarn speed and length meter YS-20 make it simple to convert from contact to non-contact or to speed and length measurement

User-selected units
Linear Speed: meters/min, feet/min, inches/min
Length: meters, feet, inches
Revolutions: rpm

The measurement is carried out, as long as the measuring key is pressed

Built-in memory for minimum, maximum and last values

Tachometer with big, easy to ready LCD display

Electricity saving electronic assures a long battery durability

YS-F - Yarn Measuring Adapter
Yarn measuring adapter with rubber coated measuring wheel and unique “wrapper” roller for speed and length measurement of filaments (max. 0.5 mm Ø) or thin, flexible wires (max. 0.3 mm Ø). This precision roller directs the filament on to the low-inertia, U-grooved measuring wheel to maximize contact and eliminate filament slip and breakage.
