TENSION METER
|
|
The
New CHECK•LINE® models ZEF and ZED employ a strain-gauge system for
accurately
|
measuring the
running line tensions on a wide variety of yarns, fibers and fine wires. Its
|
trigger-operated roller
shifting mechanism makes it easy to acquire the running material.
|
|
Single-button
automatic zero permits operation in any orientation while maintaining
highest
|
accuracy.

ZEF Models
|
Miniature
rollers make these models ideal for delicate yarns/fibers and fine wires as
well as
|
those applications
where access space is limited.
|
For
Spandex and similar materials, specify model ZEF-100-T.
|
|
ZED Model
|
This
model is recommended for all other applications where miniaturized rollers
are not necessary.
