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
Standard Features

for measurement of line speed
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.
For contact measuring
10 strips with reflective tapes for non-contact measuring
Set with 140 self-adhesiv reflective tapes, (1 Set = 4 x 35 pieces)
