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 ZED Model
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, specifiy model ZEF-100-T.


This model is recommended for all other applications where miniaturized rollers are not necessary.

  1. All models can be calibrated in cN. Replace suffix "G" with suffix "CN". Example: ZED-500-CN
  2. ZEF models are calibrated using a 0.12mm diameter monofilament. ZED models are calibrated using a 0.2mm diameter monofilament.
  3. Custom calibration with customer-supplied samples is optionally available. Inquire.
