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 application where access space is limited.
For Spandex and similar materials,
specify model ZEF-100-T. |
 |
ZED Models
This model is recommended for all other applications where miniaturized
rollers are not necessary. |

| Notes: |
1. All models can be
calibrated in cN. Replace suffix "G" with
suffix "CN"
2. ZEF models are calibrated using a 0.12 mm diameter
monofilament.
ZED models are calibrated using a 0.2 mm diameter
monofilament.
3. Custom calibration with customer-supplied samples is
optionally available. Inquire |
