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.

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.|
